No, I didn't know about the Janome Yahoo group. I'll definitely be checking it out.
I'm pretty happy with the 6600 so far, and really like how the tensions are adjustable. My old machine is a Pfaff, couldn't adjust the presser foot tension, and although I much prefer the Pfaff walking foot over the Janome one, that's about the ONLY thing I can unfavorably compare at this point. The Pfaff walking foot can be used with most of the other feet, making it a standard size and you don't have to remove the regular foot shank to use it. I find that annoying with the Janome, not to mention how bulky the Janome walking foot is, and I keep popping my fingers with it when I move it out of the way to release the feet from the shank. If I'd never had the Pfaff I guess I wouldn't know the difference. Maybe I should suggest to Janome that they make their walking foot compatible with the standard feet.
Thanks again!
