Hi Marty,

As someone that uses a MJB3 daily for 20+ years, I don't know of too
many parts that fail that I would replace with a used one.  All mirrors,
sensors, filters, chucks, and bulbs, should be replaced with new ones.
I have never had trouble buying new from Suss other than their old power
supply.  The original maker of the old 505 power supply is still in
business and will still service your old one or build a new one for you.
