After literally thousands of hours of sewing my Pfaff from 1985 finally wore out and is not able to be repaired. I still have 4 Pfaff machines. 3 are made in Germany that are excellent, I would recommend them. The "new" Pfaffs are made in China. Pfaffs were briefly made in Taiwan. My Smarter C1100 Pro was made in Taiwan and sews well, a little noisier than my old ones but I can write with it and quilt messages with it onto my quilts.
Any of my Pfaffs will easily quilt through my sandwich of front, back, batting AND photos with edges turned under.
My mid-arm is a Grand Quilter which my 12 year old grandson has been using for 3 years
