I have five s/m and my DD has one whom I recently moved in with but she does not sew, and I just recently had her's serviced. I only own vintage and ancient models, but they are all working machines. The answer to the question is which one would I keep, my late mother's 1957 Singer 401A, it's been with me all through high school and both of my marriages and my three daughters and four grand children. My second DD borrowed it for a month and made all her decorations for her wedding and I've been quilting with it for the last sixteen years. So it's the 401A
Stay safe
