Got your mii already? Want it preserved for hundreds of future generations to admire? "That's great-granma's mii, that is"?
Each one of these is hand-crafted, so in fact you can't just order one up. The artist's time is going to be auctioned off. Fantastically inefficient in today's mass-production world, and also fantastically cool. I love the idea of a hand-scuplted mii: shame I don't have a damn Wii yet (yes, I know, it's on its way).
Get one while 3D printers still don't really exist yet.
UPDATE: Here's another fella offering custom miisculpts. (Thanks Uno!)
