Like ManiacQuilter2, I have worn out a walking foot. Then yesterday while switching from my 1/4" foot to my regular sewing foot, part of the foot broke off. I haven't had that happen before, however, I have a lot of sewing hours on my Janome 4000. As long as the motor doesn't burn up like my old Sears Kenmore machine, I think I'll be fine. That was very scary having smoke coming out of your sewing machine's motor. Gives new meaning to "burning the midnight oil", or something like that. I did get a new sewing machine though.
