I have a Janome 6500 and love it. The 6600 is newer and has the AcuFeed system and is a wonderful machine for quilting. Go to Janome.com and research the information on this machine. I agree that you can buy a brand new one for about the price they are asking for the used one on Craig's List. Find a Janome dealer near you. They'll work with you on the price and they should offer a class on the machine. Good Luck!
