Check whether you can get a quarter inch foot for the 1471 first. My friend has that machine as a back - up and could not get one. The measurement of the Pfaff feet changed at about the 7550 model. If you are not worried about making the quarter inch seams it would be OK.
I traded in my earlier model Pfaff for 2144 and in some respects I'm sorry, as the earlier one was trouble free and this one won't communicate with the computer.
