Since you are asking this in a forum setting....I would recommend one for Flat Screens.

There is a lot of information and it can be overwhelming...do your homework....don't go cheap....buy once, cry once. At the very least, narrow your choice to a few models and then read up about the pro's and con's of each. No TV is perfect.
I would look for a LED backlight with local dimming for best Picture Quality....Sony is supposed to have some promising panels in 2011.
Good luck.
