Thanks for the great information. I have two Kenmores, a featherweight and a new (2years) inexpensive Singer. I am happy with all of my machines and have found a great repair person who not only knows about most machines but is very reasonable. I recently had work done on my 30 year old Kenmore and the repair man did it within a week and charged only $70 including cleaning. I had a problem with my cams and it needed a new part & a good cleaning.
