When we were in Myrtle Beach last year with a show, we got one locally from a place called Showcards. (For those who aren't sure what we're talking about, it's used for dancers/performers to tell spacing across the stage. It has numbers centered every two feet each side of center for them to guide off.) It was on a black plasticy material...my best way to describe it is it's like the molding along the base of a wall where it meets the floor - though I could be totally wrong with my description. I think the numbers were around 3 inches high, but again, I'm only going from memory. We needed about 30 feet each side of center, and I remember debating between whether to get one that went 30 to 0 to 30 (the full width) or two separate ones (30 to 0 for one and 0 to 30 the other). I think we bought 2 "full" ones, so we could have one upstage and one downstage. My PSM says they were $170-200. Showcards doesn't seem to have a website, but if you do a Google search you can at least get their phone number.
I was quite impressed with how non-bulky, lightweight, and compact they were, compared to ones we had made previously ourself on thick webbing. And we were always worried the webbing would stretch - a previous incarnation on burlap certainly had stretched beyond use.
