Well found the correct motors for Leo, less than a $10 fix, actually $7.16 before S&H. Polulu.com wants another $10.95 for S&H. I don't mind paying for S&H but would rather wait till I ordered more than the S&H is going to be. I might get a few extra motors to put on the swap board and see what I can get for them. $20 for 4 motors, or $30 for 15 motors, you do the math and see what you come up with.
