Trying to figure what my mom's Allen MDC-31 is worth before asking someone to take a look at repairing it (no sound - see my prior post if you want details).

The repair shop has a charge just to walk in the door, mileage charges and then an hourly rate.

So, IF it was working as it should, what would be the price range for one of these?

It's in physically excellent condition, as basically only my mom and dad played it. It's still sitting in the same spot it was put in 1981.

We found the original receipt for it and it cost eight grand in 1981, but thinking along those lines might make me think that an original IBM PC might be worth the two grand they cost at about that time.
