I usually do the routine stuff on all my machines myself...but, in the rare instance when I need to take it out, I have a repairman who I've been dealing with for about 16-17 years. He has a gruff personality, but boy, does he know his stuff!
The only problem I have with him is that he is so busy sometimes I have to wait a day or two more...but that too, is okay! He only charges $75 for a thorough going-over.
