I have had two Pfaffs, neither of them the one you have. Mine were (I sold one.) both Tiptronics. Love them both, but can't address the availability of parts question, because mine have never needed any service. I did buy many extra feet a few years back, and had no problem finding them, brand new. Hth. Good luck. If you don't manage to snag this one, you can probably find a good one used at a dealer. People do trade up. I'd be sure to get one with the IDT, though. The ancient Pfaff's didn't have that.
