I love my old Singer machines. They don't complain or ask if I really have to sew that today. I have 4 Singer treadles 66,201,
15-90 and 237. Even if the power were to go out I can still sew, I've done it several times. Once we were having a severe thunderstorm and the power went out(it was daytime) and I didn't know it had gone out until my Ottlite went out. I just dragged the machine over to the window and kept on sewing. :-D
4 Featherweights,a black 301,99k hand crank.
All of my machines get used, the treadles more often. I like the older machines as I can do all the servicing myself.
I have a few newer machines too. Pfaff 1222E,2040,Bernina 1031,HV Sapphire 875.
