I was going to go with front projection though the idea of rear projection seems rather cool too. I like your Spandex setup and if I plan to build my own that seems to be a fairly cost effective solution I will definitely ping you. However, If I go with that Elite model, what would you suggest for downward tension? Can this be kept safely outside year round. Also, how much black area is typically at the top as the Ceiling is 10+ feet, I'd like the top of the view to maybe start about a foot or so from the top.
Finally, are there any good motorized options without breaking the bank or do you think a manual solution to be better suited. I am new to the outdoor theater hobby but have been wanting to do this now for over a year now. We live in a great neighborhood and are all pretty friendly, so I can see this being a lot of fun.
Thank you for the info and link.
