With everything done there mate, there's about 50 hours worth of work with the mechanical / electrical included. I read the whole thread, there was a 3 stage machine polishing process (compound, medium cut, then refined with a finishing polish) which alone is approximately 35-40hrs work. Really depends on the guys labour rate, as most of the cost involved here is time.

They probably paid, including parts for the service, something like £1500 for that job.
