I recieved my dear sister's bernina 930 years after she passed from another sister and had it rehaulded 2x's . Husband bought me a new bernina 430 and not one of the many many many feet , attachments etc worked for the new one !!! ugh ! could not believe it. I would think the inner piece that the feet and attachments go on could have been kept the same ?! But, then I would not have had to buy new ones !! silly me. But I do love my bernina ! so.....also have an old serger bernina, and a brother. I'm set ! And sooooo Blessed.
