I have a 1938 Singer model 15-91 and am using it to piece the Jinny Beyer DA VINCI kit for my grandson's graduation in June. I paid $75.00 (including a cabinet) for it from an antique dealer. It has a knee control which I am learning to love. I also like to sew strips with the 3 treadles we have. But I still like my Bernina 640 for attaching binding (their walking foot works best I've tried) and for regular sewing. I also have 301's and featherweights I take to class. We are shipping 1 featherweight to my daughter's in CA just so she and I can both have machines to sew with when we go to visit.
