I have the 6600 and love it especially for FMQ. Which ever machine you buy please be sure to find a dealer who will stand by the machine. You should get classes with it, even one would be good as it is an easy machine to use. Look around for a pricing deal. There was a thread on here last week about this very thing and the ladies were getting tables and extra feet with their machines depending where they shopped. The prices were very good also. Your DH will be glad you saved him a lot of money. lol
