Congratulations on your new (40-year-old) Pfaff. They're well-made machines; it should be fun learning its features and putting it through its paces. And no bulky cabinet to deal with.
Two Pfaffs in one day? Do you live in a region with a lot of people of German heritage, or was it just a fluke? I'd be tempted to spend my free time stalking garage sales in your area, that's for sure.
