Scott is in Dallas for the Custom Entertainment Design Information Association Show, or CEDIA, where he's been seeing a lot of new home theater stuff including laser projectors. Epson introduced a low cost one last year and this year Sony joins the list. But by "low cost," Scott says that they cost around $10,000. Even the huge commercial cinema projector companies are starting to look at home theater projection, but not everyone can afford their $150-400,000 price tags. More affordable options are high brightness projectors, which offer improved illumination, for around $3,000 to 4,000. But you'll want to get a better screen or paint your wall with special projector paint like Screen Goo. That's not cheap, either.
4K projectors are everywhere now, but 3D is nowhere to be found.
