I have a Pfaff 7570! I think it is a great machine! Anything in particular you want to know? I am usually only on the quilting board so I did not see your request until now.

I know the Pfaff 7570 was one of the best machines Pfaff has put out. The 7550 is the same machine just without the Embroidery ability. If you can find one in good condition it would be worth exploring. Just make sure you are able to check it out first hand or better yet take it to a Pfaff dealer and let them check the Calibrations and all the functions. The 7550/7570 are approximately 10+ years old at this stage so be careful.
