$550 · Acer P7505 Projector 5000 lumen 1080p

Powerful projector - about six years old. The door to the lamp doesn't stay closed well, so it needs to be taped in place. Has under 800 hours on it (bulb life is 1500 on normal, I use it on eco which is good for 4500). 1080p full HD, and 3D capable if you have the correct glasses. 10000:1 contrast ratio and tons of inputs. Can be used for front or rear projection, ceiling or table mount. Lens shift and keystone adjustments for perfectly aligned picture.
