I have the Pfaff 7570 and the Pfaff 2170. I do a fair amount of embroidery and quilting, so I wanted to upgrade to a machine with a larger throat and a bigger hoop. I went to my local dealer who sells both Bernina and Pfaff. He was very up front and told me some horror stories about the new Pfaffs since the merger. He showed me the difference in workmanship between the Pfaff creative vision and the Bernina 830. When all was said and done, I bought the Bernina. (The prices were comparable) I love the machine and the dealer is very patient with my many questions. I know some are sold on others brands, and that is "what makes the world go round ".
I just finished a king size quilt on the 830 and was thoroughly satisfied with the results. Here is the link to that quilt:

Good luck and let us know your final decision.
