Oh, I want a babylock too. I have a nice serger though so probably won't get one soon. I use it all the time, for finishing edges of pants that I shorten, for going around the seams on fabrics that fray a lot, for kids clothes, and much more. Once you have one, and learn to use it, it is indispensable.
Take a class from the dealer to learn all the advantages. At my shop, you can take the class before you buy the serger!
