I am currently building a new home that should be complete in early November, 2003. It will have a dedicated theater room over the garage with an 8' vaulted ceiling that is 11'3" wide and 20'6" long. The room while have very little to no ambient light. I would appreciate any recommendations as to what projector/screen combination would be best if I want to spend $10,000 for the pair. My current plans are to go with a Stewart Deluxe Fixed HDTV 100" screen and one of the following projectors: Optoma H76, Infocus 7200, SharpVision XV-Z10000U, Marantz VP-12S2 or Yamaha DPX-1000. Should I include LCD projectors? Is a sealed light engine necessary?
