I have a Pfaff 7570 that I dearly love. I recently upgraded (kept my Pfaff) to the Babylock Serenade which is so very similar to my Pfaff. Only reason I upgraded is for the extra bells and whistles my Pfaff didn't have, longer harp, auto thread cutter, knee lift. I love it. I think it is every bit as good as my Pfaff.
I will add, I tried the new Pfaff Smarter before buying my Babylock and it was alot less machine for the same money. I will not buy the Pfaff's made in the past 10 years as I just don't think they are the same quality as the original ones made in Germany. Just my opinion.
