This is only a partial list, I am sure. Also, I can only list places I have actually purchased parts from. Since I live in the USA, that sort of explains the bias towards US based suppliers. If you know of a supplier for various parts listed, send me an e-mail and I will add it. Also, if you think other parts should be added to this list, send me email. Hopefully, all will find this list useful.
