Pfaff is part of a holding company VSP (Viking, Singer, Pfaff) and the machines are no longer made in Germany. I got one of the newer models and could definitely tell the difference in quality. (I no longer own that new machine - gave her away) That said, I know some people who bought new Pfaffs and are perfectly happy with their choice.
I changed over to Baby Lock. Some of their machines also have the built-in walking foot which looks just like the Pfaff IDT. Mine does not and it is THE ONLY thing I don't like about my baby. Funny enough, she needed to go in the hospital recently and I pulled out the backup machine (Pfaff 7550). Oh what a difference: Light is barely there. Throat space is tiny. And for a minute I panicked because I couldn't find the built-in scissors. lol I didn't do as much sewing as I had expected - rather waited for the Baby Lock to come back home.
