I have Rollei P66 - I found one in v. good condition on ebay for ~ 200$. There is one right now listed but for more $ and no remote http://tinyurl.com/c6268cp
bulbs and trays are available + it is quiet
screen for example like this one http://www.bhphotovideo.com/c/produc...atol_70_x.html or bigger like this one http://www.bhphotovideo.com/c/produc...n_x_84_in.html if you have a room.
I saw older projectors with manual changing slides but for those I saw there were problems with bulbs + they run very hot and they had much longer lenses than I could use in my location.
