I got in 3 of these projectors from a local university. They have all been tested and work great and have very low hours! One has 300 hours, one has 500 hours, and the other has 625 hours, so the projectors have not been used much at all, which also means the lamps haven't either and will not need to be replaced for a really long time.  They are also all in the same condition as the one in the listing's pics, with minor marks or scratches from general use.  Includes the RZ570 projector, standard lens that comes with them, and their power supply.
