If they work decent and have the manual and accessories and decent condition, the lowest I've seen is $250 and it had a little rust. Most here start at $300.00 and up. Went to an estate sale and the one they had was sold for $400.00. Had a Bernina there for $35.00 with most of accessories and manual. Needed work. Weighed a ton. I started to go for it but little girl got there ahead of me.
