LIGHTING, needle up/down and positionable, and oh, how I miss the walking foot feature on my Pfaff! I really like my Janome 6600P, but why did they not make a better foot system for it!? I have to remove that darned shaft to change to several different feet. What a pain! If I had it to do over again, I'd probably go back to a Pfaff, and may do that yet...so much more user friendly!
