I live in a flat which makes ceiling mounting my projector difficult. I also have the problem that the wall on the side of my projector is an internal wall and i doubt whether it would support a projector wall mount, which is a shame. I really want to put my projector behind my seate and obviously slightly above. Probably 1.5m from the ground at a rough guess. My projector is a sharp z9000 which isn't the smallest dlp around. Any sugguestions? p.s. fairly cheap would be good.
