I love my Pfaff's. I ended up with a Creative Vision for embroidery and such. I take my older Pfaff to classes and quilting get togethers.
I have a dear friend who will service my older Pfaff ... but the CV needs a special grounding pad [or some such] and she doesn't do those. Though I have had no problem with the CV.
The dual feed is what has kept me quilting due to arthritis in my hands.
So ... get the machine you bond with the best ... and enjoy.
