A great source for stepper motors are old computer printers. The old QUME and
DIABLO daisywheel printers had excellent steppers in them. Some of the big
"line" printers used with minicomputers are a good source for LARGE steppers.

Also check old tape drives, card-readers/punches, etc.

Check out your local Computer Centre for any junked or unused printers! :-)
