Thanks AudreyB. That was my one concern ... that I think I am interested but might not use it. And yes, I already love that built-in walking foot! I used it to put binding on a group quilt. It's so much easier that trying to get the walking foot on my Bernina 153. I seem to fumble around for what seems like minutes and then suddenly it's on and I have no idea how I finally did it! Do love the Bernina though.
Thanks also maryb119. I could not find anyone who had that unit or had ever used it. Nice to hear that it does work and can add to you design repertoire. Unless I get more feedback saying it is worthless, I think I will go for it.
