Oh I missed that, thanks. My local Hackerspace made some boards that have that LoRa radio and an ESP8266 on them, I might grab some of those as I'm not in the US and Adafruit won't ship here cheaply, thank you.
Yeah, that's probably a good bet. I'm in Europe and there are actually a decent number of European suppliers (or try Mouser, they seems to ship internationally for free, I have no idea how it works out for them but I got mine there).
