I wanted to see what others are using for projector screens. I noticed Amazon has decent pull down/hanging style 100in starting at $49 shipped. I currently have a 100in pull down that I bought at staples because I had store credits and major discounts. I am thinking I want to place one out on the side of my shop. I have a huge backyard, and could easily go up to 300in if I build the screen myself, but wonder if I'd be better off with the projector paint(which I know next to nothing about) i'd be happy if I can go with at least 200in for a reasonable cost. So is anyone using the Spro2 outside? What screens are you using?
