I've been curious about it, but I'm not terribly fired up to get one.
First off, it's a bit too $$$ for a single-purpose object.
2nd, I can't really see how it would be useful for any work I do on drafting film (drafting film can be molded & shaped when it's warm), and since that's the support I use the most for my Celtic work, it doesn't make much sense for me.
3rd, Where would I keep the thing? I've already run out of good places for storing sheets of paper & matboard & finished works.
Just my 2 bits.
