After Market drive motors and controllers?

I've been considering a vintage Japanese mount for my FS-128. Its the old Nikon pier mount for the 10cm ED. The price is fair and the mount is very nice. But I am concerned that if the drive motors fail I'll own a white elephant! Does anyone supply retrofits for old EQ mounts?

Thank you!

Hi,
you could add a home built goto drive. Mel Bartels http://www.bbastrodesigns.com/cot/cot.html
Provides a superlative design and free software that is adapatable to any telescope there is. There is also a yahoo group with 1600 members for support. I have 2 scopes both using this system, a dob and an gem. It is at least the equal of any commercial system out there.

hope this helps
cheers
