I seem to remember a while back there was a discussion about sources of enamel covered magnet wire. I just received a Parts Express catalog, and they have 18 through 24 gauge, prices all around $19 for 1/2 pound. Lengths vary from 100' for 18 ga to 404' for 24 ga. http://www.parts-express.com/term/nte-magnet-wire?srch=NTE+magnet+wire Bill Zukowski
