Can't figure out which projector fits these features
I would look on Ebay and Craigslist since your requirements would be met by most projectors produced in the last 10+ years. Find one that suits you, and invest in a spare bulb (or two) while you're at it, since you might be buying a used item.

Also, check out Slickdeals for clearance items, such as this BenQ DLP projector that meets your requirements: http://slickdeals.net/forums/showthread.php?t=3634482
