When buying vintage machines, check to see the bobbin cases and feed plates are there becuase these can be pricey for some machines. It's also nice to have any attachments and the manual but these can be replaced. You should also carefully inspect the cords. I just bought a Singer 201-3 at an estate sale and the cords were very brittle and cracking. I'm sure that someone would have gotten a nasty shock if they had just plugged it in. I had mine re-wired, serviced and cleaned for $70. My repair lady said one old machine literally erupted in a small fire ball when she plugged it in. Now she re-wires first before servicing vintage machines with suspect wires.
