Apex's cheap price can be explained by the fact that Apex is the first (to my knowledge) Chinese company to enter the TV market, and apparently they can afford to undercut the Japanese, Korean, and American manufacturers. With that in mind, and with just a 1year warranty (2 years on the picture tub) I'd be a little hesitant to jump on this one.
Anyway, my bad experience with one of their DVD players (and the endless hold times to get any kind of support) would keep me out of this deal.
Reviews look good, though.
