I have a Bernina 1530 in the same line and it is still my favorite DSM. I have owned it since it was new in the box. I have collected the feet over the years. I ONLY use a walking foot and a 1/4" foot so it is NOT a big expense. They all came with a rectangle box that fit into the back of the machine. Tell him the concern you have about the condition of the machine. I myself would buy it as a back up. Make sure it is in good running shape and take a flashlight and look at the bobbin case. Bernina need to be service every 12 to 18 months.
