Hi guys, I don't know squat about the projector world so I have a few questions. I did some research and one projector I'm about to pull the trigger on is the Epson 6500UB http://www.hd.ca/epsonprojectors/6500ub.php . My question doesn't really pertain to the projector itself but the screen. I was comtemplating getting a 120" screen to go with it but I don't know which I should get. I'm looking at the 120" on this page http://www.eastporters.com/estore/ca...category_id=37 . Now here's where I have questions; I have to get a pulldown because I'm going to have a dual setup with a TV behind it (for watching regular tv) so the screen might be going up and down possibly often enough. Now motorized or not ? What happens in the longrun when the motor blows out ? Can you still pull down and back up the screen ? Or would manual be better ? Does a motor typically last long ? White or grey ? Gain, they list 1.2 or 2.4, what's better ? My room is 10.5' wide by 24' long with sitting distance at 15-16 feet, is 120" too big ? I know, lot of questions but this is my first dip in the projector world. Thanks in advance !
