What I need:

  • reasonable resolution (not 640x480, maybe 1024x768 minimum, but I'm willing to budge on this)
  • long life, no need to change parts
  • connects to a standard computer VGA out

What I don't need

  • SD/USB port
  • speakers
  • color depth
  • absolute smoothness
  • portability
  • HDMI video input
  • S-video input
  • any other sort of input than VGA

In other words, minimally I need to be able to project in grayscale and without worrying about changing a bulb. So which flavor of digital projector should I be buying?

What type of environment will this be used in? Does it need to be portable? – Friend Of George Dec 2 '11 at 22:40
I wrote that it didn't. – magnetar Dec 3 '11 at 19:44
I see that now. – Friend Of George Dec 4 '11 at 2:49

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:
