I have a Janome Memory Craft 7000, it's 24 years old and it's more than paid for itself. I looked at the Janome 6600, too many features for what I want it for. It's a beautiful machine, but it would have been over kill for what I needed.
I bought a Pfaff Performance 2056, I love the IDT feature, (built in walking foot) The machine is a work horse!!
After the nightmare experience I had with Janome's customer service when my 2 week old embroidery machine had problems, I wouldn't consider buying another Janome again. Should I ever have to buy another machine, it will definitely be another Pfaff.
