I'm in the market for a new sewing machine. I have a Bernina 220 now,, which is good for piecing but not so good for quilting (short arm). I'm looking at the Janome 6500 and the Bernina 350PE; I'd love to have people's views on the two. What I'm looking for is slightly longer arm, which I think the Janome has, but I don't know too much about the company. And can I use the bobbins I have for my current Bernina in the Janome.
