$177 Elinchrom Skyport Universal SPEED set

Elinchrom’s original EL-Skyport transmitters and receivers were popular for their price and high level of control, but the latest versions have a much more robust build, including a locking collar that will make sure the transmitter doesn’t slip out of your hot-shoe. A bonus: users of Elinchrom’s RX-series strobes can even control strobe power from the camera.
