I got mine at the Big Orange Box (home depot) just dont buy any of the cheap ones that look like cast aluminum. The brass ones hold up pretty nicely get enough for all your tools plus a few extra for the tools that find their way into your tool box later. Pick up an extra female coupler at the same time to save aggrivation later on.
