Going to be upgrading my AE200 next month hopefully, I currently project onto a 92" screen with a throw distance of about 3 meters (cant remember exact numbers). I was anticipating upgrading to an AE700 but recently noted that the throw distances are drastically different, and my same 3 meters wouldnt give me anything close to 92". So a quick question, if i used optical zoom, how will it affect image quality if at all? If it does what would your suggested alternative, £1200 is about my limit, would the AE500 be a viable alternative and does anyone sell those with a dead pixel check still. Cheers guys.
