I still use my 7570 all the time. The embroidery capabilities are all I need. I am still using the vintage german 230 which is an old mechanical. I love them both. I never upgraded as the 7570 was the last hurrah of the germans making Pfaff's and they put their hearts and souls into that machine. I also have a Juki TL98Q, 3 treadles and various other antique/vintage machines.
At the start of the changeover when Pfaff sold out there was nothing but problems with machines and it made me more grateful for what I had. We were in Germany at the time and news went around fast. It just was so hard to know the quality would never be there again. Course all lovers of specific brand machines feel the same way.
Madquilter & Candace you are both so right in your thinking and we must as Candace so aptly put... use what makes your heart soar regardless of who made it, what brand it is and how much it cost.
