My old projector is nearing the end of its days and I'm pondering getting a new one rather than buy parts for this one, so I'm looking for ideas on what to look for. Here's my situation:
I'm in an apartment, so I can't do too much to the walls/ceiling. So I plan to have the projector sitting on top of a shelving unit that's 72" high. I got no problem having it upside down; I can build a little frame to suspend it from that'll sit on the shelf (or the next shelf down, but if I take it too far down, folks on the sofa start getting heads in the way...). A tabletop model in front of the sofa probably won't work because it'll have like 5-6 feet to the screen.
My screen is 8x6 feet, and about 16.5 feet from the front edge of the shelf. The top edge of the viewing area is about 89" from the floor (and 5" from the ceiling). I can move the shelves up to the back edge of the sofa, so I can pull it in to about 14.5 feet of throw if I need to. I'm not too terribly worried about light levels; I can get the room pretty dark. I'd like to fill the screen if I can, though.
So there's the geometry. The kicker is I hate digital keystone correction. Optical is fine, I love optical. But I'm not seeing a whole lot of optical keystone correction out there, unless "lens shift" will do it... but I've gotten the impression that's more for fine-grain adjustment of the lens position, not so much for angular correction.
And of course I'd like to spend as little as possible. Used off ebay is where I got the first one

So, anyone know where I can find The Perfect Projector for a Pittance?

Or even just a few to keep an eye out for?
