I have the 11000SE and the Horizon 7700. I love my Horizon very much, I traded in the 6600 after 8 months for the Horizon, I just didn't care for the 6600. However the acufeed foot is a must and since new machines have come out with the acufeed foot on them you can probably get the 7700 or even the 6600 at a pretty good price. The new Janomes have a 9mm width instead of the usual 7mm.
