I do have a projector. It's an InFocus IN26+. We ended up buying it from Office Depot because they were local. We love it. I must admit that I got my inspiration from Backyard Theater, outdoor movie theater ideas and forums, take your projector outside!. There is a wealth of information on that site about outdoor movies. Our screen is made from PVC piping and a painters canvas tarp. Works great.
