I have a Kenmore of the same age, a 158-1946 from 1978. It is a workhorse and still going strong. Yes, maybe yours needs some parts but a good tech would suggest finding a donor machine. There are so many good Kenmores out there, I wouldn't hesitate to buy one at a thrift store or garage sale, or from a craigslist ad. I have seen great machines with all accessories in the $25 range. Easy to clean and oil yourself. You will have a better machine that a new plastic one made today.
