My ancient Pfaff, Creative 1471 I bought in 1986 does have the IDT and it is the best feature of that machine. I don't know about the newer Pfaffs but I still use my old one every day I sew. It is just my go to machine. I have looked at the Ambition Essential but don't really need another machine right now. I do have a Brother sewing/embroidery machine plus a cheap Singer and a featherweight.
