I have two Janomes, the 6600 and the Jem, and I love them both. I believe the harp on the 6600 is 9". Others have told you of the features of the 6600, but what I love best is that they rarely, rarely "eat" your fabric. Maybe all new machines are "not hungry" in this regard, but the old Kenmore I used to sew on drove me crazy. You can start your stitching right at the edge of the fabric with no problem whatsoever, and they breeze over many layers while piecing. My 6600 is a dream, and I can only imagine that the more expensive Janomes are wonderful too.
