Does anybody know where to get springs for ball lock QDs? I lost one after taking it apart for cleaning. Keg outlet has them for about $0.35, but the shipping is $9.99, and I can buy 2 new QDs at the LHBS for that. I hate to throw things away when they just need new parts. Any ideas on other sources? I guess I can wait until I need to order some other things from a keg supplier and add them on.
