I am still very happy with my cheapy Brother machine. It hasn't given me a hint of a problem for over 6 years. I have sewn a flannel and chenille quilt and then gone on to several others, not thinking to clean out the bobbin case! It was packed tight with lint, but, still kept on sewing. I can even do free motion on it by covering the feed dogs with one of those slippery sliders. And it is lightweight.
