It's sad that a person with no experience would accept his information as being reliable and have work done.
My SIL and a friend of hers had trouble with repairs of their modern machines. My SIL had a short in her foot pedal, he cut the cord and rewired, not it doesn't reach the floor.
Her friend went to the same place (at the same time) and had hers "tuned" up. After paying and bringing it home, when she opened the case her tension was in pieces. All they wanted to do was refund $50.00 of the $100 plus repair bill!! :( :(
She didn't speak up, and ended up buying a new machine elsewhere. I may have done that, but I would have gotten a full refund plus the cost of having the machine fixed elsewhere.
Thank goodness you knew what to do. He could have ruined your baby! I have a 201-2 and love it!
Good luck Charlee! :)
