Jibber: I got it at Hobby Lobby. The one I go to had just moved things around. Originally it was with hobby tools, knives, blades, and diorama supplies, which was an aisle over from models. They had moved it, and it was in the same aisle as the models. It was on the bottom shelf, so you had to look carefully to find it. It was $30, but you can always find a 40% off coupon. Sorry about the poor picture.
Chrisk-k: You can use it to hold parts, sub-assemblies, or a kit while you are working on them. I used it for the first time as I was masking around the wheel bays on a kit.
I don't think I will bolt it down, at least not for now, but it was heavy enough that it did not budge as I was working on the kit.
