I bought one from Allbrands for my old Pfaff sewing machine. I love it. It's a custom fit, and it fits perfectly. If you sign up for allbrands emails, you will get a $5.00 coupon within a week or two. Free shipping too. It took quite a while to get it, but after researching the plexiglass cutting and bugging my hubby for a year, the 4 week wait was worth it.
