Well I don't know much but I can tell you my wonderful DH took me on a surprise trip last Saturday and bought me a 1941 Singer featherweight for $350.00. That included about 5 feet, the case, book and since it was at my lqs she offered to help if I have any problems in the future. It had just been cleaned and serviced in November and the tag was still on it. Did I mention she sews like a dream.
Hope this helps.
