Suzie,
I looked, and I looked and I looked before I bought my Husqvrna Viking Sapphire machine. It is not the top of the line with all the embroidery (that I would never use), but it a true jewel. It threads itself, it knots and cuts the threads on the bottom of your quilt, it free motion quilts like a dream, has needle up/down feature and you don't have a lever to pull up or down before sewing. AND it will wind a bobbin while you are still threaded and have your quilt under the needle.(Warns you when your bobbin is low. I'm sure there are a lot of good machines out there, but this one does exactly what I wanted in a machine. Give it a look if you can.
