I don't like to tell others what to do but rather offer suggestions. I suggest waiting until you find a nice real machine that meets your budget. Used machines can be options on craigslist, local buy and sell Facebook sites etc. In the meantime a hand sewn mini quilt could keep her interest. I remember having machines that didn't work and the frustration it caused. I did manage to buy myself a very nice sewing machine as an adult. As a kid I went more for hand sewing due to the non working machines.
