I also have a 6600 and really love it. Mine came with the table and I wouldn't be without it. The accufeed is so much quieter than a walking foot that is attached. I did have some trouble with my thread jumping out of the thread take-up lever, but I discovered that there is a thread guard at the top of the needle that I had been missing when I threaded it. Since I made this correction the problem has all but ended. I did not want a lot of bells and whistles that I would never use. If I need a free arm to hem something, I just pull out the portable Singer, which I also take to class.
