So I have a perfectly functioning Babylock Quest Plus with PDQ (seems identical to IDT) and three featherweights. But somehow, I just WANT a good used Pfaff with IDT, preferably German made. I can get a lightly used 7570 locally $750 or less. This was my dream machine in the 90's. But I've heard that the motherboard might go at any time and not be available for replacement or fixable. Then the machine would not sew at all. So it's a gamble, it might also sew well for years. If I got a used mechanical, it should at least be more repairable, right? What were the last German or European made Pfaffs? Are the Tiptronics mechanical? Am I just nuts? Should I just drop the whole idea? Buy a new Pfaff? Anyone have a 7570 or similar model motherboard replaced recently? Forgive the cross post to pattern review. Thx for advice.
