I really like LoRa and its range, but unfortunately the hardware is much more expensive than e.g. Zigbee or WiFi devices. Would love a LoRaWAN router but they run around ~80€/80$ and just for playing around with it it is a bit much.
You can build one with an SX1302/SX1250 and an STM MC for cheap.
I would love to buy a cheap (~50€/$) finished LoRaWAN gateway product, but those don't exist (yet) AFAIK.
