Pretty sure there are a few collectors out there itching to buy one. I think 500-600 is about right.
The John Doe public wouldn't know two shits about it, so it would probably sit on CL for a hundy.
I can pick up one for $200 in excellent condition on outside, non-working...Don't know how difficult those are to repair or if it is only a minor repair.....Don't know if I should risk it or not....Any opinions from anyone that has worked on them??
