Had them fix a Hasselblad lens: the 1/8th and 1/15th on the shutter were not working, so I sent a description of the problem and asked for repair and CLA. After a long delay they sent a letter stating they could not work on it until they had a go-ahead and they did not have my phone number or email address (they actually had both). I called and emailed them so they could get started. The lens was returned and the shutter had the same issue: the 1/8th and 1/15th were still not working. I sent it back and they called to tell me an additional part was needed and I would have to pay an additional $54 tacked onto the original repair and CLA bill. One month, two sets of insured shipping charges, and an additional $54 got the lens working.
Maybe bad luck on my part, but I thought I would get some kind of break on the extra shipping, extra time, and extra parts required for the repair.
The work ended up OK, but I would not put them at the top of my list. YMMV
