My favorite new gadgets are the Phottix TTL remote flash triggers that can also be used as a remote control camera trigger. Easier to use than trying to program Commander mode and remote modes, or if my remote Speedlights are facing away from the on-camera commander flash (such as a Speedlight in an umbrella or behind me)... plus my ringflash is not supported by the Nikon commander mode anyway, so I can use that flash, too, with the Phottix triggers. (Obviously, the TTL feature does not work on flashes if they are set on manual or lack that feature.)
