One of my Bernina 1008 mechanicals wouldn't allow the feed dog to drop and I took it in to the dealer for warranty repair. 2 weeks later I got it back and everything worked fine. 2 days later the feed dogs would not drop as the control knob just spun around in a circle. I called and said I was coming up to drop it off and have it fixed again. When I got there I was showing the nice lady who is the owners wife what the problem was and I expressed my feelings that I was loosing confidence in this particular machine. She agreed that it might be one of a batch that had some problems that they had encountered in a shipment and that she would try to get it repaired on an expedited basis. I Said," I would like to return this one to you and get a credit toward a Bernina 430 that you have on display". She said that because I have been a good customer she would give me credit toward the purchase of the 430. I called my wife and told her that I would like to spend about 1000 dollars to replace the machine I had brought up for repair, and she said. "Go ahead, whatever will get you sewing again, and resolve the problem". I am so lucky that I have a wife that encourages, and enables me, in the pursuit of this, at times, rather expensive hobby. So now, I am playing with this new machine with a gagillion stitches and bells and whistles, and having fun sewing again. Boy, it is a hassle to have a machine that is messing up on you. But oh so wonderful, to be able to resolve the problem with the help, and understanding of a life partner. Life is good again.
