You are aware this is a business orientated projector, with SVGA quality and very low lumens at 650? I dont know much about it, but i know the list price is around £2200 and you can get a SOny VPL CX6 XGA 2000 Lumens projector for a lot less. My guess is its a second hand model you are buying? What are you projector needs and what will you be using it for? What price are you looking to spend?
