SPI generaly just orders from current suppliers and resells at a markup. PIC is one of the few places I know of that list .7 Module gears as a standard item. If they are going to get them from PIC the material choices in the catalog I have are SS or Aluminum. I would be happy with either one. We ran aluminum last year in the 84-88 tooth count range with no problems. I never did run a tooth stress on it but I know it survived our pretty brutal (10 ft/sec) drivetrain. I have the impression that the standard tooth stress calculations are overly conservative for our short life applications.
