I have been sewing with a Pfaff for 12-15 yr and I would never be without one .... the IDT feature makes all the difference. My first Pfaff was a 7560 (no embroidery unit) ... I gave it to my daughter and upgraded to a 7570 (same machine with embroidery unit) .. I sold it 2 yr ago and purchased the new Creative Vision ... it is fabulous. Both of my old machines are still in use and run like a top.
I used to sew doll clothes and clothes for my granddaughters as well as mend my husband's jeans ... my Pfaff went from delicate fabric to jeans with no problem and the embroidery was great.
I have had many other brands, but Pfaff is top of the line in my opinion. I am now retired and quilt ... Pfaff does it all.
