There are two sewing machine "repair people" in the town where I live. One is capable of doing very good work but usually dumps it off to some new employee and you can't get it back for three months, so I won't take it to him any more. The other is a 40-ish person who really means well but lacks experience and he cleaned my machine and it came back all oily and the zig zag and fancy stitches wouldn't change width. I drove 50 miles to the next nearest place and got a pretty young man and thought, great another one with no experience, but to my surprise he did a wonderful job and he now has the Pfaff to adjust the famcy stitches and adjust the needle threader. Hate to drive 100 mile round trip but it's worth it to save the hassle!
