I have been quilting in the range of about 30 years. Sewed many years on an inexpensive Singer and now use a Featherweight for most of my piecing. I also own 2 Kenmores, one high end (an embroidery) and one mid-range but use my vintage Singers most of the time. They make the best straight stitch around. A fancy, high-end machine does NOT a quilter make. Encourage her to try some other types of machines, many shops that do machine repair also have different refurbished machines for sale. She may be surprised at what there is out there being offered in different machines and won't know until she tries a few. If she really loves quilting and has the desire to do it, with your help I bet a suitable machine can be found. We have such of wealth of machines, fabrics, notions, etc. that are available to us now days that surely she can find something.
