Just Resin-cast your own mini's. (Score 2, Interesting)

Sure, it calls for you to get one to make the initial mold, but in the end you get a lightweight model that is FAR cheaper (less than a dime in materials), more resilient than plastic and lighter than metal, and it's easy to mod with a Dremel tool. My friend and I cast Obliterators every time we're over at his house. No way am I dropping $20 _each_ for a model that's a little bigger than a Terminator. J
