listen if you want a TV that is going to last dont cheap out and get a POS phillips or a polaroid or a westing house or a Vizo or some other shitty no name brand TV. but that doesnt mean you have to get a over priced SONY XBR ( **** a waste of money i feel bad for the people that buy them)
look into the toshiba Regza, Sharp Aquos, and the Panasonic.
do your self a favor and get it from BEST BUY...put it on their credit card so you can pay it off with no intrest and GET THE EXTENDED WARRANTY...
Plasma will give you a better picture then LCD and it is better for faster moving movies video games and sports games ( and BURN IN is no longer an issue) BUT it does kinda **** with glare. in a dark room they are by far better.
i would look into this...
