not sure what to tell you. I got a panasonic plasma 50" and find it really amazing but I am wary about screen burn so I always play with the contrast really low.. however I find for gaming including playing retro systems and current gen and pc gaming the colours and picture quality are just amazing..

anyway if you already have a plasma then you already know the pros and cons.. such as more power consumption and when you move it around you have to let the gases settle for a couple of hours etc.. and don't turn the contrast up too high..

If you want the change and go for LED then go ahead.. but I hear they are not true LED unless you buy OLED which are much more expensive.. anyway just do some more research and buy a hifi and tv magazine and check the reviews..

My plasma is about 2 years old and I wouldn't call it that old.. I don't know much about the older generation of plasmas and only time will tell if my plasma will be value for money.. besides if you do get screen burn you can download stuff to help run in your TV screen.

I'd say go with a 24" CRT and if you have the budget you could stretch to one with built in vhs. 

My Plasma always is complimented by my LED friends and family. They think it was price, but the main difference is it is a plasma. The colors are so bright.

plasma is excellent for gaming as you will get good picture good colours and good blacks for a fraction of the price of an led

downside is they are heavy

i use a 42" samsung plasma it has lots and lots of picture enhancement options and i love it to bits, sound is naff though thats why i had to use seperate speakers

If you are going with LCD, get LED.
CCFL darkens over time, uses more power and throws out more heat, LED back-lighting will stay as bright as the day you bought the panel.
This is also a flaw with Plasma panels too, they will also darken over time.

Secondly... Steer clear from Samsungs for awhile, I have noticed they have started using cheap non-solid capacitors which can reduce the reliability of the panels, which they probably did to increase profits.

As for response times... They really are a non issue these days. LCD has come along way over the last several years, you would notice a larger difference if a game ran at 60fps rather than 30fps.

Why, that is one of the reasons PS3 is superior to the 360? You must still live at home. XD

LED obviously, plasma is good but doesnt last nearly as much as LED tech since its a gas.
LCD sucks

*face palm*
LCD sucks? Those TV's that are advertised as LED? News flash. They are LCD panels. The difference is that the light behind them is now LED.
