Astro Commander is working on a new source for his miniature models, and that might mean more advanced designs for cheaper. The ships are made out of a pewter material and have sharp pins to form the weapon detail. They're also scaled down to about an inch long to accommodate tabletop gaming.
Thought some of you may want to know, a trial run of the studio bergstrom ships have just been completed and should be available for order soon. They are cheaper and higher detail, in general, than what we can get from shapeways. I have mine on order and look forward to painting these!
