I have a Singer Touch & Sew 626 that I bought in 1966. It has been many miles with me and a very good machine. It did have plastic gears in it that broke. I was told it would be cheaper to buy a new machine but decided, with all the metal parts my old Singer had and all the plastic on the new ones, to have it rebuilt. That was in the 80's and I still keep it for a backup machine.
