For the Wii I'd recomend a 19" CRT. ;)

I have a Sony Bravia 40X2000 1080p. I think it's just beautiful, I hook up my PS3 and use it to browse my pics from my PC, they look just stunning in 1080p.

Complete BS and misinformation!
Burn in is STILL a problem with plasma, stop saying nonsense. They can call it temporary, it's still there, even if it doesn't last, so don't say it isn't a problem. Black levels are STILL NOT on the level of a CRT for ANY HD technology, so again, stop saying nonsense.

I just bought a new Sony RPTV, and RP for now, is the ONLY HD technology that looks good with SD content. The black levels are also the best of all those technologies.
That is simply caused by the technology used.
With LCD or plasma, a powerful lamp sends light that traverses several layers of electronic components. Because of that, you can't have good black levels.
Also, you have a huge (depending of the size of display) array of electronic components, which cause problems again, because it's harder to have such a big array with every component right (yield defects problem).
You have also spaces between the pixels which you can actually see. This is one of the worst thing that make you see lots of jaggies in SD content.
Also, commanding such a huge array of component causes heavy lag, which is why they have a hard time reaching an acceptable response time. When they advertise 5 ms response time, you can be sure it's actually 5 times that.
There are a slew of other problems that makes plasma and LCD suffer from various artifacts like banding, solarisation, screen-door effect, ACE, burn-in, ...

The SXRD RP I bought doesn't suffer any of these problems. You have only a few problems, like green blob when your set is too cold, or silk-screen effect. Once well set, you won't notice it anymore though, and you'll have one of the best image (though Pioneer Elite plasma are better, for 3 times the price, with burn-in and other artefacts).
The main drawback of these sets, is that they're not slim, and you won't find them under 50" size.

One thing you should be aware of: be sure to have a game mode on your TV, or the Wii will be unplayable. Most HDTV (except the 120 Hz ones perhaps) sets are just too slow, and you'll notice it right away when using the Wiimote, as the lag is immediately noticeable. The game mode removes most of the expensive treatments, allowing you, at least on my HDTV set, to not feel any lag at all, which means it's then well below 16 ms response time.

BTW, on my HDTV sets, contrary to other people, the Wii looks BEAUTIFUL. It's just amazing, with no jaggies, and I tested it with GC games only for now, which displays in 576i on my set (55" 1080p). I'll test Wii games when I have time (too late now), but I bet they'll look even better.

My samsung 42" Plasma doesn't give me Jaggies for my Wii games. Just my 2 bits.

Umm I said 'screens' which would be the same thing as 'panels'. I never said Samsung makes thier internal other parts. Just the screen itself. Which means that regardless of the other internal peices it will only look as good as the screen that Samsung built.

Let's see buy a Sony with less features that looks nearly identical for $1000 more. Sure sold.

You're right, that is complete BS and misinformation.  Plasmas do not have backlights, they have a phosphor coating just like a CRT.  The main difference is that instead of energizing the phosphors with an electron beam, they run a current through some noble gases in a plasma cell, which emits energy that in turn excites the phosphors.  Very similar in function to a CRT (but able to be built as a flat panel), and allows for very pure blacks.

Stop saying nonsense! :P

I still like LCD and will probably end up going with a 42" later this year or next year.  IMO you get the best bang for your buck with an LCD display, and I think their blacks are plenty black enough for me.  You can actually find full 1080p resolution LCD panels at prices that don't break the bank.

It doesn't matter what TV you get. Since the pathetic Wii doesnt even support high definition gaming.

Thanks for a very constructive and well-rounded post. I'm sure DiscipleInAgony knows exactly what to get...

DiscipleOfAgony,

As for the TV, if you are looking for one specifically for the Wii, you can't go wrong with either a CRT (bulky) or an ED LCD or plasma.

ED LCDs are getting harder to find and the ones that are around tend to have smaller screen sizes; Plasmas can be found but their resolution is not quite the same as the Wii's output:

http://electronics.pricegrabber.com/plasma-lcd-televisions/p/197/popup5%5B%5D=45:1661/sortby=priceA/popup4%5B%5D=10:3

There you can see most plasmas have 852x480 resolution while the Wii renders in 720x480, which is close and will reasonably mask the jaggies. As a rule of thumb, you can increase/stretch the screen about 10% without any discernible quality loss, so the plasmas in the link above are "close enough".

Having said that, CRTs are probably the best in the sense that since it is analog, it is resolution independent, so you won't have any problem with jaggies no matter what resolution you throw at it, with the tradeoff that you will not be able to find any CRTs that can output 1080p (but then again, you aren't looking for that!).

If you do go the CRT route, try to find the 100Hz models; some support 1080i as well, and do provide for multiple input options, including but not limited to VGA (for any other connectivity purposes you might have).

Good luck!

Edit: Specific answers to your questions follow...

The thing is that I still have not decided which one is better,strictly for the wii…LCD HD or SD ??

ED, or specifically, a digital TV (Plasma, LCD) that can output as close as possible a native resolution of 720x840; if you want a CRT, resolution is not an issue.

The thing is that I hear/read always contradictory things about the ideal tv solution for the wii…for example there is always the mention of intolerable jaggies in 480p..

Some people find it intolerable. I am fine with it. Basically, if you've watched DVDs on an HDTV and haven't complained, you won't complain too much with the Wii.

I have decided to go for a 32” tv and some of the options I have considered are the Samsung L32 M71,the Philips PF9631 and theSony  Bravia KDL32V2500 but I am still not sure if the use of the component cable along with an hd will improve drastically things.

Component will definitely improve the image quality. If you have a component DVD player, you can run this test yourself: Connect your DVD player with Composite cables and Component cables, pop in a DVD, freeze a frame, then switch between composite and component views. The difference is pretty much night and day.

I have the fear that when I will buy an hd and connect Wii, there will be horrible pixelation, ghosting, jaggies etc etc.

See above. If you already have a Wii, take it to the AV store where you will buy your TV, and ask the salesperson to connect the Wii to the TV and see for yourself which TV offers the best output for your Wii. 

Do you think that with an 27 inches tv, the jaggies would be lesser?

Compared to what? A larger TV or a smaller TV? Basically, jaggies will be the same if the resolution between the TVs are the same; but, smaller TVs tend to mask the jaggies better only because your eye cannot make out the differences as well. For instance, there is no resolution difference between a 27" TV with 1280x720 resolution and a 15" TV with 1280x720 resolution, but since the screen is smaller the jaggies won't be as apparent as a screen that is roughly double its size. An "optical illusion", if you will.

 With proper caliration, most samsungs can get very close to sony sets in terms of PQ. However, you will miss out on the "braiva engine" and their SD processing, but external processors, or a mythtv, can do that better.

@ Superchuck, if you think the 65 series looks good, search for the 81's. They come out late summer and have led backlights that dynamically dim, so say hello to "perfect" black levels. 

 Yes, Samsung makes the best TVs out there almost. The Sony's are damn near as good. But for a Wii. No.

Get a CRT. The bigger the better. Chances are, the more expensive, the better.

The Wii looks sub-par on digital screens. I run mine on my 40inch samsung 1080p, or my 26inch magnavox 720p. 

As far as CRTs go, look for a sony Trinitron or Mitsubishi diamatron as they offer the best in CRT tech. Sony's tvs have taken a dive in the past ~5yrs, so look for an older model Sony crt (I believe their 1998 models are considered best). downside is you dont have many widescreen options (16:9)

Generally, DVDs look better on EDTVs because it displays their native resolution, 480p, so that may also hold true for the Wii.
