We just completed this home theater for a Houston, TX family.  We started with an Epson 1080p projector that we mounted on the ceiling. We projected this onto a 105in matte white fixed screen. Then we added five in-wall speakers from Episode for full surround sound. Driving the speakers and Polk subwoofer is an Onkyo surround receiver.  Everything is effortlessly controlled by a URC MX450 Universal Remote.  It is becoming increasingly affordable to build a complete home theater for nearly any budget.
