I have a Phaff Quilt expressions 4.0. I love it. I have had it for about 7 months now and I can't say enough about how great it is. Check it out for all the bells and whistles and the quality you get for the money.
You might check other reviews areas, I know the one I went too had me very discouraged about the machine, but I did more research on it, went to my local dealer and I must say I have not had one single problem with it.
I'm sure she will be happy with whatever machine you decide to get her. Good luck
