Look for a DLP in all honesty. Plasmas that are 1080p will run you a fortune at a large size. LCD's will cost a ton at large sizes as well and I'm guessing you want 50+ inches on the screen.
Also, check on what the lamp is in the DLP, there are new ones out that do not have the rainbow effect because they use LED's instead of a lamp.

Also, when looking at the TV's in stores be careful. They are not set up to look great in stores and the lighting there can also affect how well the screen looks. Have them give you the remote and go through and tweak the settings on the TV to see if it looks good for you. Also bring with you a DVD that you know how it should look and be great and judge it from that. Alot of the streams and movies they show at stores are split either 60 ways so it loses quality, or they are "Disney" based animated movies which look great no matter the tv you play them on.
Also, careful with the information you are getting from posters with the "Wikipedia" links. They are dated and not something I would rely on. AVS is a great place to go to http://www.avsforum.com/ .
I did do a little searching on that Toshiba you listed in your review and it got some great reviews from customers and really seems to be the best big tv you can get for that price. Now I'm debating about picking up this TV just because of how cheap it is.
