You can find info about it by Googling. It's about $200 US new. Here's a description of what it's for and what it'll do (see the Features tab):

I have two compatible flashes. For me, this unit would replace the flash attached to my camera allowing it to be placed off-camera. I use my on-camera flash for fill, so on-camera is a good place for it (so I don't see a need for the ST-E2 right now for myself).

Remember that the front of the body (the red lens on the flash) of slaves has to "see" the signal from the master. In the days of manually slaving flashes, I could just put a wimpy flash on my camera in the studio, and maybe point it straight up and all of the strobes would see this simple "peak of light" signal and fire, even if I was in front of them, behind them, etc. This non-radio wireless arrangement has its limitations. It is, however, very portable and convenient when others are using flash (they won't trigger these units which are tuned to signals from each other).

I like the idea of using this with the mt24-ex and the 580ex together for macro and portraits i have found a new one pretty cheap.....then my kit will be full(doubtful lol)
