If you get a serger get a Babylock Evolve...the auto thread feature makes it a must. A serger is just a sewing machine that does a different seam. There are a lot of ways to do that different seam, so it can be very versatile. I have made quilt tops but I don't quilt on it. I have made bags, clothes, accessories, doll clothes, and it can so some limited decorative stitching techniques as well. The one you saw was on Sewing with Nancy and that show is the reason I traded my high end serger for a Babylock. It is not a substitute for a regular sewing machine but adds another dimension to your sewing abilities.
