Well, first things first...my first purchase will be a new foot control.
I was sewing, walked away to take a phone call, and wouldn't you know the machine took off on its own.
Evidently this was/is a problem with the older models.
A New Bernina foot control today's quote- $325.
Hubby researched and we are going to go with a solid state electronic version found on EBay for $59. UGH!
