I have the Pfaff 6120 and have been trying to find one on Ebay for a few years so that my daughters will have one. I've been using mine since early 90's. It has the built-in walking foot. This is the best machine I've ever used. I will never trade it in. The machine made now can't compare to what was made in the past... at least as far as quality. I think there's quite a few people out there that have the same opinion because when one shows up for auction, it sells. I bought mine for 900 dollars and it seems I'll have to spend about 700 for a used one. They sure held their value!
