Depends on how much you want to spend. Personally, at the end of the summer I'm buying this:
http://www.amazon.com/Samsung-LNT4065F-108...V/dp/B000OE02G4It's well received pretty much everywhere I've looked, has an amazing Amazon price (it's like $2000-2200 everywhere else), and it is currently CNET's highest rated LCD TV.
If you're looking at stats, make sure it has a good response time (8s is the highest acceptable speed for gaming I'd say) and a high contrast ratio.
