Now that is a foolish question! Why do guys buy tools they never use or don't even know how to use them? Myself, I have five sewing machines and can't possibly use but one at a time.
I have my mother's old, old Singer but I have managed to keep it in working order. Got one out of an old attic - it works. So its just a collecting thing. By the way, I do not have a featherweight. B
