I am a new Pfaff owner, the quilt expressions 4.0. It almost exactly similiar to my Viking 875Q, but alot quieter, handles all threads well. It uses the same bobbins as the viking. I am now convinced that Pfaff is a much better machine. I love the larger feet, love the IDT. I bought it on Ebay from a Pfaff dealer, and their customer service is awesome, I wonder about servicing though. The closest Pfaff dealer is about 150 miles or so away. I am selling my Viking 875Q, if I can part with it.
