I think I'm going to have to jump on these new deals for the Infocus 4805 and 76" screen, but need a little advice first. 1. My primary seating will be approximately 12' from the screen. I will probably start with the free 76" screen, but how large do you think I could go at that distance? 2. Does the projector have to be ceiling mounted? I have an air duct that drops down about 12" from the ceiling about 10' back from the screen wall. Assuming the projector's throw distance would be more than 10', I would have to drop it down at least 12"-14" to clear the duct. Or could I just set the projector on my bar which is behind the primary seating area? 3. I've never actually seen an in-home projector set up so I'm a little nervous about making the switch. Right now I have a 57" Toshiba with HD directv and DVD's on the Zenith dvb318. I love what I have, but would like the larger picture and am having a hard time resisting all the raving reviews and current deals. Any lst words of advice? Thanks!
