I have been looking for a solution to support sheet goods while cutting them down to size and ran across the veritas panel platform kit. I don't do a lot of this so working off the floor is ok for me; the benefit over a piece of foam board is that it stows away as a small package. Combine this with the low profile track clamps which fit if you use 1x3's for the platform, and it is a great solution.
I don't want to sound like an advertisement, but I couldn't be happier with this so I thought I would share.
