I contemplated getting a serger last year. You want the new ones that are self threading. They are ideal for sewing clothing with beautiful finished seams. They can be used for piecing but the overlooked thread edges can make a slightly more visible seams under the top. Some people use the overlock seams as accents on the top of the quilt top and that works well. I decided to buying a better Benina sewing machine instead of the serger and couldn't afford both. I don't sew enough clothes anymore to justify the cost but I would still like one.
