I've finally decided to make the jump and get an HDTV Monitor. I can't spend much more than $2,000. What's the best TV for that kind of money? I don't care about size too much, but I'm hoping for something over 40 Inches. I'm mainly gonna use it to watch DVD's. I've been looking at the Sony 46" and the 51" TV's, and the RCA's look nice, but I'm just not sure what else is out there, and what people like. Help!
