I was a little apprehensive to get one for $30 for my new machine last December, especially seeing how much money I just spent on the machine. The saleswoman couldn't have been nicer though. She suggested I get one (I machine sew on one side of the bindings and hand sew the other). She even stated that if I didn't like it, then I could return it. I absolutely LOVE, LOVE, LOVE it and couldn't imagine how or why I didn't use one before. Good luck with your decision!
