1) First of all to all the people here giving good links and info for projector mounts: THANKS!

I think you are right, my mistake, 1/3 is much better, thanks!
>>In my setup, my screen bottom is at the same height as my eyeballs
Yeah I have done that 3 years ago, since the screen was also too close, my neck still aches thinking about it

>>You could put the PJ on a low table, too.
Since I do not have a hollow (wooden)floor but concrete, I find all the cables running to the center of the room (where the table should reside) such a mess.

Wall mount is due to roomsize also not an option. I am going for a ceilingmount but will probably build my own (with the given links as examples) since I also want to fit my ISCOII anamorphic lens on it for 1:2.35 source. I hope the zoom on the Toshiba is large enough for this so I can fix the projector position.
