Do your home work. Dealers stopped taking this model as trade in on a new machine for a reason. Janome also stopped making it long before they normally phase out machines. The sole plate was a big problem, malfunction and broke needles. They suggested a replacement, but don't remember the outcome of all of that. There are other Janomes, gently used out there, that have better reviews. I had a 6600 when the 7700 came out and I was so tempted, but thought I would wait since it had a lot of new features not tested well......I felt like I made the right decision. I purchased the 8900 SE when it came out. Great machine, no problems. Loved it for free motion, still do. But now have the 15000. Wonderful machine as well.....still have the 6600, what a workhorse.
