Ebay has them, local camera shops may have it. I got one off of ebay that has 2 pc ports and a test switch, and gives me another hot shoe, the nikon as 15 *or what ever its name* only gives one pc and uses up the hot shoe. But if you want to keep your automation for the flash, youll have to buy the one meant for your camera. Like if you have a newer canon slr and want to use a canon flash, youll need a canon hotshoe adapter.
