You could also tell her that the machine can only do what she tells it to, and that SHE is the creative one, not the machine. I do most of my piecing by hand, because that is relaxing for me. When I do need to use a machine, I have an inexpensive Brother machine that gets the job done. It has about a hundred stitches, but I only use a few of them. I have made many quilts, and they have always turned out better than I hoped. The whole point is, she doesn't need expensive to be creative. The "first" quilters didn't even have a machine, and they had quilts that turned out beautifully. If she enjoys the quilting, then tell her to focus on that aspect. Quilting is about making something beautiful, not what kind of machine you have. Just my opinion, though.
