I have Bernina Machines. They are pretty pricey, but in the long run well worth every penny. I take them every two years for their "well baby check up" and that's it. I have a 153 QE, 440 QEE, and a 530 QE as well as a serger. I do FMQ on the 440 and the 530. The 440 is what I use on my large Bernina quilt frame. Probably will never own anything else.
