I have the Janome 6600 and it's a dream to sew on. It has the start/stop button that you are talking about. You have to unplug the peddle to use it, but since I have trouble with my right leg, I don't mind at all. Knee lift for the presser foot, needle up/down, auto thread cutter, lock stitch, and speed control are some of it's features. I also have the 760 for taking to classes and camp. If I ever buy another machine, it will be a Janome. And I like the price of them too.
