yeah I'd stay away from a $700, 15 year old projector, lol! Unless it's a $650 screen
*edit* oh holy crap I just googled it and that's the first projector I ever owned! Back in 2002, when I was working in the A/V Department at my old college, my boss sold me one for $50 that came out of a classroom they were rennovating. It had been installed in like 1995 or so.
It was 640x480, and believe it or not, only around 70 lumens if I recall. Less than 100. You had to have the room completely blacked out, but then the image looked halfway decent. It was a monster though, weighed like 50 pounds. Had motorized zoom and focux, lots of high end features.
Would definitely be a very bad choice for outdoor theater, though. Look for an infocus X1 if you want something used and kinda ghetto-cheap, theyr'e still a decent projector for the money.
