My mom bought a White machine back in the early '50's. She sewed a lot for herself and me and it never went in for repairs. It was a "cabinet" model where the machine itself went down into the cabinet and it made a decent-looking piece of furniture in our living room back then. Mom died in 1993, and I sold that machine for 15.00. The lady that bought it didn't even sew, just wanted it for the table that contained it.
I've been kicking myself ever since. I have 2 computerized machines, which seem to give me some problems occasionally. That old White iron horse was great. The only thing I did keep is the little screwdriver that came with it, and I use it every time I sew. It's the best.
