I have the Bernina 440. Did you end up getting one? I love mine. I have a Janome embroidery machine so I didn't need that with my Bernina. Did I mention I love it?
I haven't used the BSR a lot yet. I was busy making dresses for my daughters wedding so I used several of the other features. I'm hoping to get busy using the BSR here soon and finish up some tops I have.
