The following set is relatively future proof and is what I'd buy if I were buying.
-60" LCD with LED light source (no need to replace bulb every 2-3 years (I hear prices for bulbs are falling, however.)
-At least 10,000-to-1 contrast ratio (15,000 is better).
-HDMI 1.3 inputs (two on back of set, one on front).
Make sure the "glare screen" isn't actually ADDING distortion to the picture. Get inches away and look for grain like you're listening for distortion in a speaker.
I'm amazed how many big screens have this "feature".
The best (smoothest) picture I've seen is a Panasonic 61" RPT retailing around $2500 -really fine picture.
Finally, make sure the CPU processor is fast enough to avoid
picture "break up" on complex scenes.
Motocross, marathon events, anything with lots of images moving together quickly can overload the CPU and the picture just falls apart (more like explodes) into a pathetic mess (high definition my ass...).
