Ace Hardware is another Good option for a lot of tiny hardware like the springs. I have improvised using them a few times. You can also find a few springs in old cassette players and video players. The biggest problem for me is tying the knots on the string. What I have been thinking of doing is to use a pair of hemostat clamps to hold the loop and apply a glob of Super glue. The reason is you have to have some tension whilst doing this on the dial spring so it wont slip or be loose and sloppy.
