It is nice when you can win one. Yes high school girls can destroy sewing machines. I bought out a school's machines one time - I think I had a good dozen of those Singer 404 machines - none of them worked. I got all but 2 two to work - those two donated all kinds of little parts for the others. I suppose if I bought parts the other two would work - then again I don't know I let Wilbur at one of them with a screw driver once. Anyway here is a link for one of the last:

Once they sew they are nice little machines - great for learning to sew - not very heavy either.
