Schill 93: Ditto what Irishgirl and Irishmom say about the Janome 6600 Accufeed foot. I have had my Janome 6600 since 2008 and it has been an amazing machine. In January of this year I had to replace the thread cutter mechanism as it was just worn out. It had cut a lot of threads in the past 11 years! The only part ever replaced!
Besides quilting I also make handbags, wallets,cushion covers, home dec items, etc. I have even repaired a camping tent. The accufeed food is also excellent in sewing thick fabrics like canvas, denim, and outdoor fabric. Also multiple layers like thick handles on a handbag, or zippers in cushions are a snap with the Accufeed system.
