Hi As you may have read in another post, I sold my TV and I am going to buy a Infocus Screenplay 4805 projector. I am on a tight budget (in the $200 to $250 range). I would like to get a screen instead of using the wall, but I really have no idea what is good and what isn't. It seems like the pull down screens are the cheapest. I am a little leary about those. Do the stay flat enough for viewing or do the edges curl up? Are they better then the wall? Anything else I should be watching for? I like the idea of pull down, because I can hang movie posters behind the screen and raise it when it isn't in use. If the pulldown screen sacrifices quiality I don't need it that bad. I am thinking that I need a 16:9 screen that measures around 90" to 100" diagonal.
