Have you asked the dealer what the differences? That is where I start. I have frequently found that one could be an earlier model by only a few months with a few different stitches that I would not even consider. The last Janome I purchased was only different by 3 decorative stitches. It saved me $900 getting 3 decorative stitches less. I have never missed them. I love my Janome and would recommend them to anyone.
