The stick on my SFIV Tournament Edition Fightstick was getting loose, and my accuracy while playing SFIV was suffering. But now, thanks to a 95-cent LS-33 spring and a very helpful YouTube video (http://www.youtube.com/watch?v=L67fUfH3S5o) I've performed my first mini-mod, bringing back both the springiness to the stick and the accuracy to my game. Awesome. Plus, a lot more satisfying and cost-effective than replacing the whole stick. Hadouken!
