I have a Janome 6600 and do free motion all the time. I have found that I need to set the upper tension at about 3-4 for regular piecing and 5-6 for fmq, but I do not use the single stitch plate or any special bobbin. With any machine you buy, you need to find what works for you and your style of sewing. I say, just buy the one that feels right for you. That's why there is such a variety of brands, styles and prices out there. Good luck and happy quilting!! :lol:
