It depends on what you will be sewing. For only quilting, probably not. If however, you intend to do garment or home dec, yes! If you intend, for instance, to make pillows with ruffled edges, a ruffler foot makes beautiful easy evenly spaced ruffled. You don't have to sew 2 basting threads,then carefully pull up the threads to distribute evenly the ruffles. Also, if making curtains, you can make the ruffles and attach it to a second fabric at the same time. I have several for different machines. Bottom line, if for what ever project, you intend to be making lots of ruffles, it is worth if for just the ease of making ruffles.
