I love my Janome 6600. It has never not done what i've asked of it. I quilt on it a lot... teach FMQ on it, and make bags with it. I love the integrated walking foot for doing bindings. I even purchased a 2nd one so when I sew with my daughters at camp, we have 2. My third machine is a Janome 10000 sewing and embroidery machine.
Good luck with your search.
