I'm kind of new to this HDTV thing, so please excuse my ignorance. I need help in finding a good HDTV. I'd like around a 45-52 inch widescreen rear projection. I have about 1700-2000 to spend. What I'm really looking for is a TV that is for all around general purpose. I'd be using it for Xbox gaming (so I'd probably want one with 720p capability right...?) and also for displaying DVD's and normal cable broadcasts. I'd like one that could convert digital cable in 4:3 mode to fit on a widescreen with minimal stretching. What models are good, and what company should I go with?
