You think your 46-inch HDTV is big? You think it's a nice way to watch movies? Eh, it's OK. If you were really serious about your home theater, you'd drop $175,000 on a projector serious enough to be put in a movie theater.
The JVC DLA-RS4000 can put an image on your wall up to 21 feet in size, making that LCD TV of yours seem downright puny in comparison. The projector can handle 4K resolution, which is four times that of HD. Sure, there isn't any content out there at that resolution, but by the time it is you'll be all set. Totally worth it!
