There is a Singer 66-16 for sell by the granddaughter that was gifted it, for 50.00. She says the cord needs replaced but that it does have the foot control. No attachments in the cabinet other than a button holer. The cabinet is in nice shape. My spouse is willing to rewire it for me. How hard are the bobbins and feet for this model to find? And is it worth 50.00 considering the dearth of accessories and needing rewired?
