Shirley, I also shop the thrift stores. The DAV is next to my pharmacy and everytime I go there I drop in the thrift store. Haven't found anything good lately. About a year ago, I stopped into the same thrift store and I could hardly believe my eyes. There were two Kenmore machines in nice cabinets and one Necchi in a really nice desk type cabinet with three large drawers on the side. The Kenmores were in good condition, but I never tried them out as I have a Necchi that is 57 years old and I was interested in the Necchi. I tried it out and everything seemed to be fine. I paid $29.00 for it and it sews well. The only thing that I can't get to work, which is really why I wanted it, is the knob that drops the feed dogs won't move and I don't see anywhere that I can oil it. I suppose that I will have to have the shop take a look at it. I also tried to find out what year it was made, but everything on line did not give me a clue. Good luck with your Thrift finds.
