Thanks for the responses. I didn't really expect to be able to do 3D before the screen arrived, but wondered to what extent the quality would be diminished - or if it wouldn't work at all.
That said, what have your experiences been like with 3D? Has it been good for business? I know better than to expect miracles, but I'm excited to be getting it. I think there's only one other second-run theater in the state doing it, so I like the idea of doing something different, offering 3D at a low price, etc.
