Hi Joan, I just had my Viking #1 serviced to the tune of $171.00. I burnt up the brushes in the motor, I also got a great cleaning job done on it, also timing, new needle, adjustments to everything, you name it. She purrs like a kitten. Part was$20.00 labor and the rest of maintance was 151.00. So I really can't tell you if it is expensive or not. Maybe with a fancy machine the cost goes up. If you love her as I do mine, just bite the bullet and enjoy her, and start saving for the next repair job.LOL OXOXOXOX glo fr. Calif.
