I have had your situation. Several years ago I had to replace the mother board in my Bernina 1130. It was a good choice because I really liked the machine and it is a real workhorse. The machine is now 29 years old and still works perfectly. I also had to replace another computer board at some point but I knew it was worth it. To replace the machine with one having the same capabilities would have cost several thousand dollars. If you were to replace your machine you would probably have to replace some or most of the attachments you use to quilt with. Even if you buy the same brand the attachments you have will not fit your new machine. It is called planned obsolescence. Be sure that you count all of the costs before deciding what to do. I would also recommend that you take it to a Bernina dealer and technician rather than just a sewing machine store that deals with several brands.
