I have a 1941 Singer that I use for EVERYTHING....since I've never mastered any of my newer machines! It doesn't jam, it doesn't come unthreaded, and it's very predictable...which I need since I don't have that gene for figuring out mechanical stuff! It recently lost the ability to make bobbins when the little tiny burr of metal that holds the bobbin on to wind finally wore off too much....so I bought a bobbin maker. Love this baby!
