Gatorfoam board in Ultra White,

Where do you get it from?

There are others that have used this as is or as a paintable substrate. I ran into a problem in my area as far as availability.

At $50, you're right there at a sheet of Designer White, and for a little more you can get a larger sheet. Talk to Clarence, HG57 and some of the other guys that have CRT projectors. Clarence has used a wide variety of screen methods and can give you personal first hand input on a level those of us with digital projectors can't.

Out of curiosity, where did you get the 1.3 gain figure from?

Thanks for the reply adriankelly, I was curious is all because I haven't seen any gain tests on this. That doesn't mean it's bad, just I was curious where the 1.3 figure came from.

I couldn't locate any in my area, and $92 is a bit more than I wanted to pay for a 4x8 substrate sheet, but the main thing is if you like it and are happy. If you can remember who and where you saw the gain test done that would be great
