Hum. Some of them present a good amount of work, others seems a bit.... approximative. I mean, the idea of masters for bases is not bad, nor new, though. They could focus on something interesting (as cobblestones, why not) instead of gluing sand or electronical devices on a round base...
ah, and another think: writing "this is the positive impression that the Basing Pad produces from its Negative sculpted detailing" is ok, but not when you're obviously showing the master of the mold! ù.ù
