Thanks for the responses! I'm really on the fence about it, I used the heck out of my 6600 until I acquired a juki. Just seemed to me as the 6700 would be the best of both worlds. I really should see if a service might help the 6600 perform better, it is eating fabric like crazy, seemed to have gotten worse after the last repair☹️ . The easy change plates appeal to me, not sure about the accufeed feet, they seem kinda flimsy. The dealer is willing to part with the floormachine (6700) for 2k . I have the feeling that I wouldn't use what the 9400 has to offer. This machene is not stocked by the dealer here in town.
