If anyone could give me some feedback on the right sort of screen for this projector I would appreciate it. At the moment I am looking at two screens: Elite Screens TE106HW2 CineTension2 Electric Projection Screen (close to $900) and the Elite Screens ELECTRIC100H Electric Projection Screen (around $170). The room the projector will be installed in has contronable ambient light, the ceiling paint is white and the walls are gray (dark, but not as dark as some other colors). I suppose if anyone could offer any suggestions either between these two (is the price difference something felt in the quality of the two?). Is there some other type of screen I should be considering (I am near ignorant on this subject). Any feedback would be appreciated. Thanks!
