I work for a distributor and we get a pretty good discounts on Infocus stuff. I am debating between the 4805 and 5000. I can not find any local place to actually go and see these units so I am in the dark on both of them. Has anyone actually seen the 5000 in action? I am mainly concerned about the screendoor effect as I have heard that is more of a problem with LCD based machines. I wish I had $15,000 for the 777!
