Lucky you! I have a 7570 I wouldn't trade either, and I just bought a Performance 5.0 last month. So far, I really like it. I bought another Pfaff because I've been so happy with my 7570, which I've had since 1995. Have bought a few other brands since the 7570, but decided to go back to another Pfaff, since I've been so happy with it.
Enjoy!
