HI!
I have been sewing for many years and quilting for about 12 or so. I have a Phaff that replaced my Kenmore. Though when I started doing more quilts I got a Janome (it was at a discounted price - new model came out). I also got an embroidery machine and that is strictkly used for embroidery. Look for a machine that suits her needs and don't be afraid to look at higher priced models - look at them for to compare differences of what they have to offer, more stitches, more feet, threader, auto cutter etc. You don't want to buy a machine and then in a few months she's out grown it or decides she really could use those other options. I love my Janome and had planned to eventually put it on a frame to do quilting with but ended up with a babylock on it for quilting. Hope this helps.
Best of luck,
Pam
