Include an inline water knock out pot. I like quick disconnects, get more than a few and keep them handy as you always need an extra one. I prefer the one sold at Sears.

There MANY different makes and when you buy a new tool, you'll need a compatible male end. Nothing pisses ya off more than a QD that don't fit.

Nice to be able to reach into a bin and pull one out. Use Teflon tape on the threads.
