I have a Brother Imagine which I got on sale for $1500. I traded in an older model. It is my third serger. It is definitely the best and I consider it a bargain since it is hassle free - It adjusts it's own tension, it threads the lower loopers itself. It doesn't have the cover stitch, but I really don't need it and I use another stitch instead. Sometimes with my old serger - another brand- I would have such a hard time seeing the place to try to get the thread to go and then the tension would be wrong that I would cry - finally just put it in the closet. What good is a machine in the closet? I consider using a "basic" sewing machine like asking a secretary to use an old non-electric typewriter instead of a computer. Why do it?
