Like the title says, I want to watch movies outside this Summer. As this will not be a heavily used projector, I don't want to spend a lot, I have my 60" TV for most movies and games. So, around dusk, it would be fun to watch a few movies outdoors with the family. I've been reading about DIY screens, so a projector that would be visible and watchable on say 100" screen. Any input is appreciated, and thanks.
