The TV is cheap because it's a rear projection (i.e. awful), if all you're concerned about is having a big screen at a low price and for some bizarre reason you think having 3D is a good thing then I suppose it's OK. For everyone else it would make more sense to buy a 50" plasma of some sort (low end 720p ones are quite affordable now).
DLP? umm no wonder its so cheap. People do you realize how expensive the lamps are in those suckers? For anyone that watches a decent amount of TV dont expect to get 3 years out of a lamp then its 400+ out of your pocket for another one.
