I run a front projector, and have a 120" screen. If you can control the light, I think it is hands down the best approach.RogerRabbit said:Bulbs are still expensive to replace, e.g. $400, however they are rated on most models for 2000-3000 hours of use. I have read the operating costs are $0.20 to ~$0.50/ hour. If you want cheap, stick to old tube technology or if you want wow, go LCD projection...amazing for gaming if you have a big enough room...
As for "old CRT technology", in my opinion, CRT still rules in a lot of ways. However it is bulkier. I think people are buying lcd and dlp as they think it is better, but they have some serious compromises. I think manufacturers prefer these technologies though (cheaper to produce, less warehouse space, etc). There is a reason why animation is used to demo a lot of the digital display formats...
