I have a Bernina 640 and haven't regretted it for a minute. (I didn't buy the embroidery unit) It has some pretty neat tricks that make quilting faster... like the foot pedal. Tap the foot pedal with your toes once and it will stitch once. Rock the pedal back on the heel and the needle will go up or down, depending on what you have your needle set to do. I use needle-up while sewing but when I reach a corner I like the needle down to pivot. All I have to do is rock the pedal back, needle goes down and I don't have to move my hands at all. I don't need to move my hands to the flywheel, I can 'tap' and keep going. The knee-lift, I think they call it hands-free sewing, I wouldn't give up if my life depended on it. I love it!
