I had a Janome before I bought my Bernina 440 this last spring and before that I had a Bernina 930. I would never give up my Bernina. I don't miss the Janome at all. I figured I have never had a problem with my Bernina the 25 plus years I had it. My store wasn't very helpful either, but I have talked with other dealers and they have all been very helpful. Actually the person I bought mine from is a lot better now. I guess we just needed to get to know each other. I am in the process of buying the laptop I need for the 440QE. Can't wait, because there are many quilting and embroidery stitches I can utilize in my quilting.
I would go with the Bernina myself. PS I still have my 930 and would not give that one up either.
