I would only buy a vintage Singer sewing machine that is not plastic or has plastic parts. I have several that I have picked up at flea markets, thrift sales, yard sales etc. I bought them for my grandchildren to learn on but once we cleaned them and oiled them, I started using them. I have pieced on them, no heavy duty quilting, but I do believe they can handle it. I took one to a repair man to adjust and he had no problem doing it. These old machines are work horses, they can handle just about anything. I love anything vintage and these are fabulous. Several women I know have bought them too. Even my 1916 Singer works great. Just stay away from the plastic sewing machines, they aren't very good.
