AP 800 Restore?

I recently had My AP180 restored and now I'm wondering if it's worth the expense to,restore the AP800 mount that it came with. It needs a hand controller but they're much too expensive $800. I wouldn't mind restoring the mount since it was original with the scope.
I've also considered replacing the DC RA motor with AC synchronous version and using an old school drive corrector.

Any ideas or suggestions?
