Unsound makes a good point...if your going to mount on the rear wall you should look for something that does not vent out the rear of the unit.
You will also want a projector with the correct throw distance for your fixed location, ie...you will want to be able to adjust picture size up or down if needed. The mount should fit somewhere near the middle of the adjustment range for "that" projector...they are not all the same.
Good budget screen http://www.carada.com/....you can also make one for around $100-$200 which is what some people do at the (AVSforum) Unsound mentioned above do...all kinds of plans at that site.
Word of warning about the AVSforum!...some members are like some of our members....they do more tweaking than watching, (or listening in our case)..HeHe
