I have the BERNINA 780 (two years) and it's an absolute dream machine. The dual feed feet are perfect for piecing and the huge "M Class" bobbins, especially with thinner 50wt thread like Aurifil, lasts for hours before needing to be refilled. I sewed on several other manufacturers top of the line machines last week at the Houston International Quilt Festival in all day classes and can say, unequivocally, I was glad to return home to my BERNINA 780.
