I agree with most of the responders-I own the 6600 and my sister owns the 6500. I'd spend the extra money for the 6600 or try to find a trade in with a reputable dealer - maybe for less. I also own the 7700 and like all Janomes it is top notch. I don't think you'll go wrong with any model, but long haul, I'd get 1 with accufeed system because you will want it the minute you use it.
