I have the 7570 and have heard about the mother boards...... I have had mine for 10 years now and use it all the time. Have not had any major work done on it, but I have a feeling that something is going to go at some point. I just hope it's not the board, 'cause I would be lost without it! Not all of the Pfaffs have the IDT, so check that out well. I also have an older Pfaff without the IDT and can never remember what model it is, It is a push button, without a mother board and is about 30 years old, no major work, still a great machine and had it on my table top frame prior to upgrading. I'm not sure when Pfaff went to the oriental country for manufacturing, but I'd join the Pfaff community on Yahoo! to find out more information. Good luck on your search. Also, the price for that 7570 is FANTASTIC even today. Does it have the embroidery unit with it?
