Kim $75 including the part seems pretty reasonable to me. The machine tech in my area charges $79 just to clean, oil and adjust a machine. If it needs any parts or more work that will cost extra...maybe you got some lint built up and it pushed your bobbin case out of wack? or some fabric got caught in it? I agree with quilter68..check it out at the shop before you take it home to make sure it is working properly. Happy Stitchin' crafty_linda_b
