Summary: I shopped for this particular unit after experience with one at work. The one I bought said it needed a new lamp, so I was rolling the dice a bit, hoping that was the only thing wrong with it. I replaced the lamp with a new one, and hooked it up to my laptop for a test run. I was very happy with the brightness and clarity when projecting it on a lightly textured sheetrock wall in my home. After being assured of the unit's functionality, I later bought a remote for it.
