I love my vintage machines, I have 4 singer treadles all in working condition ( 2 model 27, a model 9w, a model 66 -redeye), and 4 electric- that mostly gather dust or make some repairs when i'm in a hurry (a singer model 201-2 that's frozen and in need of cleaning, a white domestic- currently awaiting parts, a free-westinghouse that needs cleaned but runs, and a more modern brother that I honestly haven't ripped apart yet).
I love the treadles and that's why I use them for almost everything. I don't know if I'll ever buy a new machine again, the plastic parts wearing out/ jamming, just don't seem worth it. :)
