I too, am a very happy Janome owner. I have two 6600's that I free motion on with the blue dot and never a problem. I also have a 4900,9000,3160 (for class) and a 350E. Never had a problem with any of them. The 6600 is a workhorse. LOVE this machine as you can tell...have two of them. Keep one at the cabin and one at home...too heavy to lug around. I would not trade the 6600, not even for the new 7700.
