I saw these today, and I'm thinking on gnabbing one or two. They even have many of the kinds un-painted, and the base one that is sold unpainted also.
Robotstore.com also has promo codes, but I can't find them online. I'm ordering their magazine/catalog to see if it will be printed in that!
Shipping is a bit on the steep side, even for stateside shipping. for two of those buggers, it was $10.55 USPS priority mail options.... after I saw that, I have now stopped my order and I'm going to wait and try to find a promo code.
These things are pretty big~ Most are over Twelve inches (30.5cm).
