I have the Bernina that was my mother's. it is about 30 years old and a work horse. It was the top of the line at that time and her dream machine. I have used it for the last 23 years and don't plan to replace it. I had to have the motor replaced a few years ago and I asked the Bernina repairman was it worth repairing and his answer was yes. To get a comparable machine was about three times more than the repair. I would buy another one if they were in my budget.
