I agree with several others on here about the IDT on the Pfaffs. I would rather sew on the Pfaff (an older one bought in 1986 and I sew on it every day I sew). It does not compare with sewing with the separate walking foot I have to put on my Brother. I am looking at the new Pfaff Ambition (I think that is the name of it). I use the IDT engaged on nearly everything I sew. It will sew through thick or thin, never failed me. Our local dealer is fantastic.
