I take my 15-year old Pfaff for servicing in Pensacola and it's $50.00. I take it in every couple of years. I also have a Bernina 440QE but's it too new for servicing yet. Also have a Viking Mega Quilter but I use it so infrequently now it still does not need servicing. Think I need to go to "sewing machine servicing" school.
