I got the Z200 as my first projector too, but wall mounted mine. It is extremely heavy, so you will need a good joist above
This is a page from the manual, which shows how far you can shift the image.
I also found the projector central calculator
http://www.projectorcentral.com/Sany...ulator-pro.htm very useful too.
I also found a US thread, where people post their best image settings. I'll check mine and post them later, as they made a big difference to the preset ones.
My sig below, shows my Z2000 wall mounted. When I get a new camera, I will post some pics of it in action. The picture is amazing, but maybe once a week I have to slightly adjust the focus. It doesn't bother me and is probably because of the pounding subwoofer
