All manufacturers make the same machine in 'good' 'better' and 'best' so the Brothers in Wal-Mart are not the same Brothers in Jo-Ann's usually. Knowing that I think I would have bought the next model up. If she really gets into sewing having a machine with limited options won't do her much good.
Saying that... I did buy a Brother from Wal-mart when my old one die. The most expensive mechanical there as I sew little. Because it is all plastic it is loud and has little weight and sounds like I'm going through the floor with it as we have hardwood floors throughout. It does gets the job done but I would want a better machine if I sewed a lot.
