I have taken old ugly machines and worked and worked and now they shine and smile at me. I have 33 and can't think of a one I want to get rid of. My original that DH bought me when I was very young is a Touch and Sew. I still go to it for my sewing. But I have taken very good care of it too. Someone will want your machines to refurbish. Sears still sell old parts for old Kenmores. I have several and am just waiting on 3 parts for a pretty machine. Sears are reasonable on their old parts too.
