My husband bought this machine at least 20 years ago and I loved it, especially the built in walking foot. When I started quilting I found that I really wanted a larger bed for more quilting room. I ended up giving it to a friend who's life was heartbreaking. I do remember being warned about the motherboard problems. It didn't have a drop in bobbin which was a very minor inconvenience. I don't recall a knee lift or needle down. I think it cost $2200 at that time as husband was unaware that sewing machine salesmen will dicker just like a car dealer. Based on my history I think the your asking price is a bit high.
