I just used one of those for a super bowl party temp installation and it worked out really well - 123" image with the lens just ~58" from the screen. The top of the image was about 10-12" below the projector, which is something I hadn't expected, since I'm used to 'conventional' projectors. It was just a little Optoma gaming projector someone gave me a while back...I don't even know the model number. But the people thought it was the coolest thing in the world.

crosen - it sounds like you're looking to drop the projector and screen by the same amount, and I *highly* doubt that's what you actually want/need to do. I would think (based on past experiences) that you'd first set your screen limits to drop that to the desired height, then you'd drop the projector to the point where the top of the screen is at the same height as the top of the lens when the projector is level. That amount would likely end up being way less than 60".
