I have a very basic Brother serger. If you do other sewing than quilting, GET IT! if it's under varranty. These things are expensive new. For Quilting I use mine to finish edges before binding; before washing new fabric; join backing pieces; to finish edges in small, not-so-fancy utility items like potholders, bookmarks, kitchen towels and place mats. Otherwise for garments, curtains, for anything with long seams, anything stretchy. T-shirts take no time at all to make, knits.
