How much should I sell this machine for? Sewing Machines Parts and Sales in Los Angeles

It’s in gorgeous condition and works perfectly. It has a knee pedal and recesses into the table very smoothly. It’s just missing the wood piece that fits over out when it’s dropped into the table.

I had it given a once over (and had some gears replaced) by an awesome sewing machine repairman when I first got it. It was great as a machine to learn on, but as I got more serious about sewing for my baby I wanted a modern machine that would be easy to find new attachments and things for.

I just want to list it on a local buying and selling site and have no idea what to ask for it. I can’t even remember what we paid for it, so that’s no help. Any ideas? 🙂
