Good to know about J Hittle.
I ordered the Free Motion Supreme Slider from them and some little rings thing that go in with the bobbin to stop thread nesting. The instructor at the quilt class had one and swears by it. Her machine is same name brand one model better than mine. So...I'm going to try it. And I brought a box full of needles. Can't have to many needles. :D
Thanks everyone for your input!
