I'm not so sure that's a foolhardy or complicated project to look into. I mean, it has everything! The DLP, the color wheel, the lenses, the power supplies, I even see a VGA and video inputs. The only thing they say is missing is the light source. And if any community is qualified to scrounge up a cheap light source for a projection system, it's right here.
The only questions I have would be A: does it even turn on, and B: would the quality even be acceptable. Early DLP systems SUCKED, much like early LCD projectors did. Especially some of the color wheel projectors. If this system is capable of making a decent image, it's no more than some are paying for an LCD monitor to put in their projectors.
I admit to being curious, but not curious nor solvent enough to take the risk to buy one of these without knowing more.
