I imagine one gets what one pays for, also. If one place charges less to CLA a complete camera, as long as it is fully functional, than another does for a shutter-only CLA (not a practical option for Medallist), the latter is probably spending more time, for good reason.
I will check with Dan Daniel but from his list of capabilities and services I don't expect him to be the low bidder ;@).
I have two, one almost converted to 120 feed (still 620 take-up), and a second unmodified. I'd like to CLA both, keep one & sell one. So 'basic' CLA makes more sense to me.
I did the 120-feed conversion myself based on a phone conversion years ago with Ken/Bald Mountain. He explained it wasn't magic...all hand tools, about 30 or 32 he acquired or made over the years as needed. He told me enough to understand how to proceed...not step-by-step, but how to figure out what was necessary. Mine works but still has a bit more friction than I like with 120 and definitely 220 film...which means more material needs to be removed.
Also have sheet film back & several film holders - to keep with 'mine', the converted one.
