Also - not all of the "old" style feet are interchangeable.
I have a Bernina 1006and an old Bernina 530-2 - the Bernina 530-2 willl use the feet that the 1008 can use - but the 1006 will not use the style that came with the 530-2.
I have thought that a part-time occupation for someone could be to be a liquidator for sewing/quilting enthusiasts.
