What kind of TV to get for Mass Effect 2?

I currently have a crappy $80 pawn shop square TV and I just use it for video games since cable costs too much at my dorm. With games coming out like Mass Effect 2, Red Dead Redemption, and Final Fantasy XIII which really push the boundaries of the current gen systems I figured it’s time to upgrade. What kind do you recommend for Mass Effect 2? My current kinda blurs the text when I play Mass Effect 1 and I want something that will make it a bit more cinematic. I don’t want to spend too much money either, I was looking at this one here:

What do you recommend?

Can one recieve any kind of extended warranty on a refurbished television?

I am looking for at a Phillips TV from their outlet. Its a 50′ plasma.
