Had one back in the 70's till 2000 and never saw the inside of a repair shop. I took all the abuse I gave it too. Traveled thru many a state while moving around. Sold it when I got my 1st embroidery machine and I'm still kicking myself for selling it. Tried to buy it back for twice the money and the gal wouldn't accept my offer. Guess she realized what a jewel she had. It was a work horse for me while sewing clothes for my daughter and myself all those years. Didn't get into quilting till afterwards but I'd still take it back after all these years. Broke the little knob on the top but glued it back. Don't recall ever oiling it but I must have if it needed it. Elna made a great machine back then and still does. I now have their 945 serger and its never seen the inside of a repair shop and its over 20 years old.
