50-55" LED TV for gaming - What should I get?

#1
I have a 10 year old and a 15 year old who do a lot of gaming with their Xbox 360, and since we received a gift card to Amazon for $1,500, we want to buy a really good HDTV. What are some good options that are made for gaming in sizes 50" to 55"? Sony? Panasonic?
