Well to start off, I'll be ordering my first projector tomorrow, a refurbished 8500UB. Now in my particular room situation a wall mount would be extremely handy, more-so than a shelf as it is going to need to sit out decently far. However the question I have is, are there any wall mounts in which you can have the projector upside down so the arm is supporting the projector like a shelf rather than having the projector hanging as you would traditionally with a wall mount? Thanks! Also, budget of less than $100 would be welcomed!
