Hi Sandy. I have never really felt compelled to buy one. I think of it as something to use with knit fabrics when you make clothes. Maybe if I studied into it I would find a reason to own one, but I put my eggs in a different basket by getting a Sweet 16 for quilting. I use a Janome MC9000 for the rest of my sewing and a Featherweight for workshops and teaching children and occasional use. I can't justify the cost and don't know where I would put it. But I'm sure lots of people have them and can give you good reasons to get one. I use my regular machine for fleece and since it doesn't need to be edged, I don't understand why you'd need a serger for it. Bottom line, though, follow your heart, and do plenty of research talking with folks who use them.
