I have had both the 6600 and the 6700. The 6700 has nice features if they worked properly but my vote would also be the 6600. I understand the new 6900 sewing only machine is $5,000 and quilt shops will not be allowed by Janome to offer them lower so as far as I am concerned they can keep them. They also have to have a completely different table than the 6700 so that is even more expense.
