It depends on where you are, how many of the accessories you have, whether it's locked up or works and if anyone really wants one. If what you are showing is all you have, then I agree with Kalamaquilts.
If you have the disks, the manual, the feet, the foot pedal and electrical cord and it everything works, it would go for about $100.00 here in Texas. 401's in the case go more quickly. The ones here that are in cabinets are asking in the $100. - $150. range, but no one is buying them. They have been on Craig's list for weeks.
