I have the Pfaff Hobby lock. Got it 16 years ago. Use to make clothes for the grand girls when they were little. Loved to make them nitties with the ruffle on the bottom. Ruffling is so much easier with a serger. One step stitching. You can attach and ruffle all at the same time. Now I do mending for other people and like to serge the hems of pants before turning them up to machine stitch. Makes less bulk and sets flatter without a bulge showing on the front side. I keep my serger covered right next to my regular machine, so it's always handy. Have made a couple quilts by serger only, but takes lots of thread. No problem with getting the seams to set flat however. Makes great seams on pillow cases. I could not survive without my serger. Got it as a demo from a quilt show, so the price was right.
