For heavy use, like the quilting that we do, it is recommended to have the machine serviced at least once a year....My dealership charges $60 + the cost of parts. I recently picked up one of my machines, and because of a major klunk and such, cost $145. But, I treasure that machine and it is the 1st repair I've had on it. Normally, just tune-up.
Isn't it worth the cost to baby our sweet little machines?
