Are none of the other TV sizes listed quite big enough for you? Or maybe you have a dedicated, light-controlled room and just want the biggest picture for your buck. In either case, the answer is a home theater projector.
Rear-projection TV is dead, but front projectors are still going strong, and their picture quality and value are better than ever. These light cannons work best in darker rooms with specialized screens, although newer, brighter technologies make them versatile enough to take to new frontiers -- think backyard cinema, bowl game party walls, and big-screen gaming nirvana.
If you're new to projectors, check out "Projectors vs. TVs: Giant-screen pros and cons," and if you're considering a giant television instead, you might want to read "Don't buy a jumbo LCD TV, buy a projector" for some perspective.
