I can't pass up a deal when one comes along. Every machine I have I got a great deal on. I have a basic Janome I love for classes, Pfaff 7570 love for the dual feed, Singer (a 66 - was free but needs a bobbin case, would like to get it running because it runs so smoothly), Featherweight, engine smokes so need to have it looked at, and old perfect condition Elna Supermatic, Pfaff 1027 don't use so will sell, 2 Viking Sergers...which I love, but will sell one when I decide which one I like better, and a Bernina which is my main machine.
I guess if I see a sewing machine I want to give it a home, then if I don't use it I pass it along.
