I love my Janome 6600. It has the integrated walking foot, which is wonderful. When I SID, or sew on the binding with the walking foot, it's so much quieter than a regular walking foot. On my previous machine, when I'd use a walking foot, I was afraid that the whole machine was going to fall apart, it was so loud.
When my old machince was in for repair, I was given a low end Janome as a 'loaner' and even that had a much better feeding system than the small Brother that I owned. When I went in to pick up my repaired machine, I traded it in for the 6600.
