I saw these on Craigslist, Nashville. They are not mine nor do i know the owner. They are Hughes JVC 335s and weight about 400 lbs apiece, use 6600 watts of electricity at 240 volts and produce 3500 lumens of image. These units can project an image upto 50 FEET diagonal screen size

If you have never seen the inside of one, here is a link to Curt Palme's video projector forum, where a fellow has used one in his home theater.
