You know, I'm on the Yahoo Brother group and lots of those gals have Walmart Brothers and love them. I'm not a fan but I won't bash most of them either because it comes down to how you use the machine and what you expect out of it. Also, whether a plastic machine is any good depends on whether it has a full frame in it or not. If it does, it should last 10 years or more. Remember, we have become the throw away society. Nothing today is made to last like our vintage babies. If it doesn't have a full frame, it might last until the warranty is up if you don't hit a pin or try to sew a heavy seam. I think you made a good choice for that particular child.
