I too just got the 6600 earlier this year and DH would definitely have a coronary if I mentioned upgrading - again!! Have not seen the new one yet (am afraid to go and see it) but I am too old to spend more money on machines anyway. Neither my daughter or DIL sew so I will just stick to my 6600. Now, if I can get myself over to the store and take those free lessons on using it, maybe I will be more productive and less frustrated!
