Within the last few years, I got into projectors for gaming and movies in the house. I've tested quite a few Projectors from low to high end. Working in Broadcast, I've also been able to test some of the nicest (larger) projectors that are currently available to both vendors and consumers.
One of the units I do like is the Optoma GT1080 Darbee Enhanced Short Throw projector. The unit has a Darbee enhancement module inside that really does wonders on the output. It's short throw, so it'll work 4 feet away from the wall/screen.
You can go large with a Barco type projector, but it'll cost you as well. Someone here mentioned the Chinese junk, but not all of it is junk. I've had no issues with the Elephas projector that takes in 1080p signal, but the projected output is 480p. Still had great picture quality and I use it for movie nights with the family (indoors and outdoors).
The best deal that I've recently come across is the 1080p Top Vision Projector. It'll run you around $150 -$200 bucks, has a LOUD stereo speaker on it and looks great. I'm looking to buy this one and utilize a DVDO Iscan Micro to upscale this as well.

The key question you need to ask yourself is what your expectations are for a projector. I have a Barco boxed up that I won't use due to the sheer size and the setup needed to calibrate it. Epson models are low-mid grade as well, and their 1080p/3 LCD lineups are great as well. Me, I tend to go cheap and grade on how versatile the unit is in case I need to move it.
