I have two (2) Radio Popper Jrx transmitters in very good condition that needs a new home. The transmitters, when used along with Jrx Studio Receivers, can control the power setting of Nikon and Canon flashes and PCB monolights (Alien Bees, White Lightnings). Perfect for the strobist. Asking $65 each + SH + Paypal fees. Thanks for looking.
