I’m a Bernina girl through and through. But, that being said, I don’t think these machines really compare. I think you’re going to get a lot more for your $ with the Janome, and I believe you have a good bit more sewing space to the right of the needle. It doesn’t look like the Bernina has a needle up/down position, and to me, that’s one of the most important features of any modern day sewing machine. The catalogue mentions needle positions, but I don’t know how far to the right/left the needle goes. I love that it has a small freearm for tiny cuffs, etc, but I wonder if you’ll miss some of the features of the Janome? Have you considered the Bernina 330/350? Do you quilt or sew things besides children’s clothing? The Janome may make those tasks a bit easier.
I think it all comes down to what you’re ultimately wanting – Bells and whistles, or simplicity and durability? You’re considering two great machines – good luck choosing!!
