I've used both types (cam locks and the ball lock style, both stainless) and would suggest going with the cam locks from the start. I'd also suggest going with Oetiker clamps for the connection to hoses, over worm clamps. With the Oetiker clamps, you WON'T get cut hands. I've had enough cuts from worm clamps to hate them with a passion now. You can get the clamps, and crimp tool from Keg Connection. You can also get other crimp tools from Amazon. McMaster-Carr also sells the clamps (wide range of sizes, each covers a small range). You can either use the crimp tool to cut the clamps to remove, or use a pair of tin snips to do the job. I've done both with ease (which I use depends on my mood and which tool I grab first).
