Last year when I took a machine in to the service dept at the local machine shop, the price started at about $100 and then went up! Depended on how much they would do. The one I chose because of the problems with the machine cost me $189. When I bought a serger at this store many years ago they advised me to bring it in once a year. I told the woman at their prices I could do regular maintenance and save the cost of their service visit and get a whole new machine when it did finally die.
