I want to buy a projector under $500 for my husband for Xmas. We have a Mitsubishi 73 inch we love and don't want to replace. I'd like to buy the projector for a gift but something we can use less frequently than our main tv, movie night, stuff like that. Do u have any recommendations? This all started when I read about the 3m roku device but I figured I could pay a little more and get something better than a novelty. Also, looking at screens, I saw some that are designed for outdoors. Can they be used inside? I need something portable that's large, over 100 inches that is easy to set up. Thank you.
