I love my samsung (55ES7500) but right now prices are not very good. I've been helping my mom pick out a set for the past few weeks and everything seems about 800-1000 more expensive then when I bought mine in february. Probably because all the new models are out and all last years are long gone. Best bet is to wait a few months until Black Friday (Nov. 30) as we get some pretty good deals here around then. Last year the black friday deals blew the boxing day deals out of the water.
EDIT: Oh yeah, and check out this site for TV specifications, descriptions and reviews.
www.televisioninfo.com I know that I plug it in pretty much every TV thread but it really gives you a good idea of any TV's performance that you are looking at.
