Samsung HC-R4755W 47-Inch HD-Ready Rear Projection TV
Best value in HDTV out there
Bought this TV with some skepticism, but the reviews were good so I figured I'd take a chance.  Got the TV, hooked it up, and wasn't all that impressed, but then I ordered digital cable with HD channels, which was key, DVDs also look outstanding.  The picture looks great, the sound from the TV is better than expected and so I'm very happy with my new big screen.  Admittedly, the TV itself isn't the best looking thing in the world, but I wasn't willing to pay triple the price to impress my friends with a plasma.  In a nutshell, I don't think you'll find a better big screen TV for the price, I wouldn't be hesitant to buy this TV, but just make sure you have a good cable or satellite signal.
