Hmmm well I have two Pfaffs - The Ambition I have had for two years and an older 2038 that I have had for ten years. I absolutely love them both. Pfaff was the first with IDT (essentially a built in walking foot) that is wonderful.
I cannot tell you about parts because I never needed them. I can get all the accesories I could want with no issue.
So Pfaff still makes a great machine.
