Eastwood also has a powdercoating system. Actually, they have a couple of them.

I watched a program (it may have been My Classic Car) where the guy demonstrated using the lower priced system. He did an air cleaner lid. He made a little rack to suspend it from and after applying the powder he put the rack into an old oven that he had in the garage. It turned out really cool. I haven't personally tried it yet but have been thinking of getting one. I'm not familiar with the Craftsman one.
