I've said it before, I'll say it again.

Any town of any size will have at least one starter/alternator/generator
rebuilder in it.  Instead of buying a rebuilt unit, go visit them.  Have
your existing unit rebuilt and save a ton of money.  My Vanagon starter
took exactly $35 to be repaired four years ago.  My experience with
'rebuilt' starters has not been a pleasant one.  Spend your money locally.

Typically the local guy will replace the bushings and brushes, clean up
the amature and the solenoid.  Might even give it a coat of paint.

Check it out.  You will probably be pleasantly surprised.
