Anne, Casting is NOT that hard to do if you just want to cast SMALL stuff. Once you get into casting car/truck bodies, and LARGER sized parts, THEN you need to invest money! The small starter kits from Micro-Mark are VERY convienient to try starting off with. Plus, Gregg has run a few articles on simple mold casting, wheels and stuff, that should be easy to copy. Try it, it's cool to use stuff YOU MADE yourself,plus it CAN be a point of pride in knowing you MADE it!
