Check out projectorcentral.com for info on projectors. They seem to do quite a good job of researching them. As far as screens, the Da-Lite, Carada, and Stewart all seem to be popular choices. I've seen some DIY options and the paint on ones as well. If you can't have absolute control over the light, the new Mirage screen I saw at CEDIA was freakin amazing. Like looking at a LCD or Plasma. We want to get a hold of one to test as we are curious about the overall performance but it is something to keep your eye on.
