I decided that I'd prefer using the homemade one instead of spending the 32 for one. I was taught in a class how to use some tape, thumb tack and a pencil eraser (the ones like on top of a auto pencil) and it works great and does the same thing. You just move the thumb tack depending on how large you want your circle and it's universal. I don't mind buying things for my machine but if I don't have to then I don't.
