Annoying When I Want To Hem Something

I have pieces of sewing machines all over my house. Most of the pieces are there, but not all of them, Of course I do not discover this until I want to use them. One is missing the front dial, Another is missing the thing that holds the bobbin in. A third is all there except for the pressure foot, which is sort of needed. Pieces which were taken off by curious children, or lost by me. It is hard to say which, Missing pieces nonetheless, Annoying when I want to hem something once or twice a decade. So off to the store I go when I want to fix something or make something or something. To pick up another sewing machine. As you can imagine, I always buy a cheap one.
