I have an old beige Kenmore. Just had it fixed after my labs knocked it off the table. The repair guy said that its one of the most sought after models because it has a nob on top that instantly changes the pressure from heavy to none so you can do heavy canvas or quilting.I had bought the machine used ($25)without a manual so I had no idea. When my labs knocked the machine over it pushed the nob to most pressure and was eating my quilt when I tried to sew (I was doing applique)
