Definitely read twisted's writeup above!
As mentioned, HD-ready indicates no HD tuner. If you plan on watching "TV" over digital cable or satellite, (or any separate box, basically) then you don't need the tuner, and can save a couple hundred bucks.
Definitely go 720p or higher. Newer 720p LCD and plasma panels are 1366x720 instead of 1280x720... Best bang for the buck" right now looks like one of the Westinghouse 1080p LCDs...
