A number of years ago I bought a Singer Feather Weight II. It is the machine that goes to class and travels with us in the rv. Reasonable weight for carrying around. Practical stitches; nothing decorative but the product looks as good as my high end machines. Only one problem. I have to remember that the II needs me to do different things than some of the other machines: hold the threads when you start to sew; start to sew on fabric or there will be a mess in the bobbin case. That sort of stuff. It is one of the plastic machines. The innards are generally not metal and the outside is absolutely not metal.
I am glad to have it even if it is not my Bernina or my older Elna. It does a good job at what I ask of it.
Hope I have helped,
Pat
