I recently purchased the BenQ7700 clone, Toshiba mt700. Not sure if you are interested in a DLP projector or not since your list only has LCD projectors. But I live in West Chicago and would be happy to setup a viewing for you.

Hi, I am new to these forums as well as projectors. I have just purchased a Toshiba MT700 from crutchfield, which they also give you a free 80" screen. I have already mounted the screen seems like a 4:3 though :(. But, anyway I am trying to stay away from ceiling mounting but to use a shelf. I was going to mount the projector close to the ceiling and mount the projector to plexiglass hanging upside down. I was going to mount the plexiglass to a nice shelf board and use extended L brackets so I can fish the wires behind in a wire channel. The reason for mounting the projector upside down closer to the ceiling is because I have a big window behind my head. The room is actually quite dark so ambient light is no problem and controlled. Some questions I need help with are as follows: 1) Has anyone done this before with this projector? 2) Does anyone know what type of screws or bolts that screw into the Toshiba MT700 projector? 3) Is what I am doing okay or should I get a ceiling mount? If a ceiling mount which one? Thanks for any advice and information...
