Did some looking on Shapeways, and boy, there's lots of good stuff! Weapons, heads, all sorts. I don't see the articulated Fisto and Jitsu hands that used to be on there, though. Someone's finally gone and made Filmation Multi-Bot body parts, so if they don't get around to him officially, I have a chance at making one. But again, I think I'll wait until teh lien is offishully kill'd. I hate doing a custom, only to find that an official product comes out a year or two later.
Now, if only someone would make the triangular weapons rack from Castle Grayskull . . . .
