I'm thinking about having a custom 1:18th head sculpted and wondered who I should go to and how much it might run?
Who is it of and do you have pictures? Gig has a thread going for head ideas...maybe after he's done with the list he might help you out. Plus there's always this site which isn't too shabby on the quality -

The guy that did the Larry Hama head is Dreadnok Rocksteady from the Stank...I pm'ed him for his email addy to provide to you guys, but I haven't heard back from him yet.
Maybe you can convince Sith_fire to sell copies of his.
