Persoanlly. I'd let her not get into quilting then. Seems she's never going to be happy, and will always use her not having 'some' fancy new thing as her reason she doesn't do well.
I've been quilting on an old machine, bought in the 80's (computers were just being added and I told the salesman I wanted a MECHANICAL machine)
IMO, I don't quilt to show the talent of my machine, but MY talent.
I have a couple of spare machines, the same model, for parts, and they were in good working condition and less than $100.
