Z-Wave Radios

Why don’t I see Z-wave radios for sale like XBee radios? It seems like Z-wave is winning the race, yet shops like Adafruit, Sparkfun, etc don’t sell it. Is it a much more complicated device to develop on?

Z-Wave radios are a proprietary radio typically only available to manufacturers. Z-Wave command classes are also available to registered companies and are proprietary information.
