Since I bought a TV mostly for the Wii, I decided to get one which can display 480p content without the need for scaling. I ended up buying a 32' CRT for half the price of an equivalent LCD.
It displays a better Wii image than any other TV I've seen. It also supports 720p and 1080i through HDMI, so when I bought a 360 there were no regrets.
