I am not familiar with that Bernina but the feet for my Bernina are about $50 each. I don't know if all the feet are interchangeable with all machines but keep that in mind. I know the new 820 or 830 use different feet and bobbins? Check out the eBay listing of machines similar to yours to get an approx. value before selling. If it is in good working order, I would keep it for a backup machine.
