the HD tuner may not be worth it but take a VERY good look at the screen. I would have much rather paid another $ 500 if I didn't have such a reflection ! in anything other than near dark, I can see everything in the room in my screen and in normal daylight, I can almost shave.
I just picked up a 42 inch Sony LCD for the bedroom, which is where I'll be watching most of my movies from here on out...
