I am looking at buying a BL Serenade. But I'm having issues with finding feet, accessories and bobbins for it. I have read a lot of good things about this machine. As a former owner of many Pfaff's, I love the built in dual feed as opposed to a detachable walking foot. I currently have a Janome 8900 and not liking it. Does anyone know where to buy accessories for the Serenade? On bobbins, I've read that Pfaff bobbins (9033-P) will work with it. Do not want to buy a machine that is limited because I can't have all the toys that go with it.
