I've had a serger for 20 years - use it for garment sewing but mostly for making drapes, curtains and nightgowns. Have never used it much for quilting unless I was tying quilts - in a hurry, it works great for edging rather than binding, if you are using them for utility purposes. Also, have used my serger for making blankets for show animals. They do have a purpose, but not for pieced or aplique quilting - just my opinion.
