Hey guy's I'm new to the whole audio thing. I've done lots of searching with no real help. So here we go. I am wanting a new tv so I went to BB today and seen the Panasonic 720p th-50PX75U. For the price looks awsome, two of the sales guys claim they have the same tv. How reliable are these tv's, Is this a good tv? Should I get the 4year warranty for 299.00? Thanks for any help!
