I'd wait till next summer before getting a new (or used ) projector. By then the popular no-name chinese projectors that are selling at the prices now (around $90 or so on amazon) will feature higher resolution panels so the picture quality will be better.
I can't recommend which atmosfear fx since i don't really know what room or what motif you're going with. They have both whimsy and scary projection videos. Also, we use shower curtains (white, not frosted, is preferred imo) as its cheap to buy and available everywhere. You could also use white vinyl tablecloth or even chiffon fabric. again, it depends on the application and whether you want to see the material or not.
