In this area we only have one repairman, that is kind of reliable. The other one oiled a motor and it ended burning up. I won't go back to him. The reliable one lets younger ones repair most of them. The last time I took both my machines in the came home dirty, and a list of things they did did to them. No parts, had a bur somewhere and a small piece of thread somewhere. I clean the bobbin area everytime I change the bobbin, put a drop of oil on the race, oil every so often. It cost 89.00 for each, they never seem busy, I think they do everyone the same.
