Just had the same problem with getting my machine worked on. I took it in May for its annual cleaning and that cost me 185.00, then 92 days later it stopped sewing, took it back they said the timing was out 90.00 then 2 weeks later it was squealing and it sounded like it wanted to seize up...they had it for 3 weeks and said they couldn't find out why, so they oiled and checked the belts another 26.00 bench charge. You are right, they have you coming and going. Thinking about learning how to repair machines myself!
