Pocket Wizards, no, I'm too cheap. I use shitty ebay slaves that you should never ever ever buy because they are the most frustrating things I have put in my camera bag. I strongly suggest SkyPorts. They are a cheap (relatively) alternative to PW's and in my experience have never once showed any signs of being less reliable than PW's. I've shot with both, SkyPorts are what I'll be upgrading to.
