I have the 6600 and love it. Whatever you decide on, make sure you can get good service close to you. Buy from a reputable dealer. I also have the Brother 1500 which does amazing straight stitch only and is wonderful for machine quilting. It is pretty near exactly like the Juki 98q. I use both machines a lot and by the way I love the Accufeed on the 6600. You may want to join the Janome 6500/6600 Yahoo group. Tons of info and discussion there.
