ViewSonic LS820 Short Throw Home Theater Projector

““The ViewSonic LS820 is a full HD (1920x1080) 3D home theater projector with two killer features that fully justify its $2999 MAP price. The first is its ultra-short throw, which lets you place it on a table within inches of a wall-mounted screen, run data and power cables to it with no more effort than connecting an HDTV, and have a far bigger image than you can get with any comparably priced TV--even if you include the price of a screen. The second is a laser-and-phosphor-wheel light source with a 20,000-hour life in Eco mode and a three-year warranty.””
