I was given a singer 15-91 on Thursday and had my husband re-wire it Friday evening so that I could get the few missing parts coming. I placed an order that evening and received the parts in Monday's mail. I have never been so impressed with the speed of a company's mailing as this one. If you have an old singer needing parts give Sew-Classic a chance. Their service was exceptional, their prices great and their shipping cost were miniumal. I am thrilled to have a working, sewing machine and am going to get started on some Christmas projects.
