I'm new to the projector world. I have a 63" Samsung TV now and am thinking of moving up (so to speak). Anyways, I am very interested in the Epson 3010 but am wondering how difficult of a time i'm going to have with positioning given that it doesn't have lens shift. I have started looking at mounts and some of them have options for moving the mount around once it's installed. Is this option in a mount able to make up for not having lens shift? BTW: what mounts (wall and ceiling) do you guys recommend?
