I have recently upgraded to a used but condition infocus 4800 projector. Now I have to find something to do with my old projector. it's an older lcd projector built in 1995 from sharp. I've had it since last June, it was given to me by my father who's company was switching over to newer products. It didn't have a manual so I started to look on the internet to try to find out what I can about it. That's what got me into learning about other and newer projector's which led me to the infocus. After researching and finding about what other's think about the older technology. I'm not sure if I could sell it. I'm not sure why however, even with the screen door effect I don't it gave a bad picture. actually I thought it was pretty decent. Not as good as my hdtv but better than plain television, and it had many features that many do not have today. It was sold at 9000 dollars back then and I'm not sure how that equates with today 1200 dollars projectors. In any case I came to this forum to get a few ideas if possible.
