Depending on your budget and how much embroidery you really plan on doing, I'd suggest getting two machines. One for sewing/quilting and a separate stand alone embroidery machine. Machine embroidery is a whole different animal. You need embroidery thread, embroidery bobbin thread and stabilizers just as a beginning. If you use a combo machine there's much work involved with changing settings, adding the embroidery unit, changing the foot, etc. every time you want to switch between sewing and embroidering.
