I'd start that list with Wade KJ4WS.
Not to slight anyone else, but Wade was kind enough to do some work on my
Argonaut 505 and did an outstanding job on it, which the current owner of that
rig is still ecstatic over. (Not to worry, it went to a good home, and that
transaction served as part of the downpayment on my Omni VII)

I would look for other options - 3rd party service. I believe there are
some guys on this list who would service your rig and that is probably the
best option.
It might be a good idea for us to collectively compile a list of those
folks.
