They just take regular, Pfaff bobbins. You can order them from Sew Classic. Similarly, the 130 takes low shank attachments which are very easy to come by. Is there a specific attachment you're looking for?
I'm on the hunt for an original spool attachment for different threads for mine....
Also, if you go here
