Hey, first post here, so bear with me. I need to buy a portable projector for a business room. The business room has a large glass table and we'll be showing presentations from DVD's, as well as hooking it up to a top of the line laptop to display that image. we have $3000 USD to spend on this projector. I'm also looking for a screen that comes out from a large cylinder horizontally. Not sure on what size for the screen yet. Any posts in the next bit are appreciated.
