I have the 7700, I had the 6500 but wanted to upgrade because of the throat, I really like mine because I do all of my own free motion quilting, Also like the thread cutter and lights, only thing that I do not like is changing the feet that are not snap on. There is a metal piece that is in the way of screw. Maybe my fingers are to large but it is difficult for me. This is not a problem that I run into a lot because most of the feet are snap on and they work fine,
Otherwise I like everything about the machine.
