Hi, I had my computer driven Viking serviced for $100 last year plus $39. for parts. They do cost a lot more than the old mechanical machines. Remember the person who looks at your machine gets paid about $50. an hour plus the store has to make a profit. Repair personel have to learn about each brand because they are all different and the equipment they use to check things out can be very costly. So you may find a cheaper place next time, but be aware that there is such a difference in quality.
