I'm putting in a permanent Sim in my garage that measures 14'W x 25'D x 9'H. I am hoping to use just 12-14' of the area for the simulator. I have a 8.5'H x 10'W impact screen on order. I "had" an BenQ MX819ST projector purchased from ebay until the seller just cancelled my order 12 hours after my payment. Now I am on the search for a new projector. My first option is to place the projector on the floor in a box, the second option is to place it on the ceiling. Looking for a projector that won't break the bank. Any recommendation (new or used) is greatly appreciated. Looking to mount the projector as close to the screen as possible to maximize the space and to avoid any shadows.
