i have a little repair shop a couple of miles up the road from me i use if i get stuck with something. I used him to sort out the front mech on my proflex as for the life of me i could not make it shift properly. When i dropped it off his eyes lit up as he had not seen one for years and how he wanted one back in the day. when i picked it up he had given it a once over tweeked the gears the brakes and oiled everything but only charged me for the front mech. He said that he just wanted to make sure it was going to last another 20 years.
