I have a Bernina 1530 and never had a problem but I have heard that replacing some of the computer components can run into some money. She might want to see if she can e-mail the Bernina dealership and see if he can give her an estimate. You could also call Bernina of America customer support and see if they can give you any sort of an estimate. Berninas do hold there value so it is not like investing money into a cheaper built DSM.
