Cool but I don't know if I'd pay that much for just a head.
And I don't know about anyone else but I don't see how their pricing is a "sale." $198 + 71 (the "sale" prices for an original head + stuff to make another character) = $269 & technically those are "sale" prices. But it's on "sale" as a combo (head + additional stuff to make another character) for $269.
Still, pretty awesome looking thing & an interesting idea I'm sure someone in China is stealing to mass market as I type.
