I like Heltec V3s as they are inexpensive, widely available and each unit can be configured to any of the world region frequencies. I print my own cases, but V3 cases are widely available too. I actually prefer MeshCore to Meshtastic, but the V3 is supported by both.

I've also found MeshCore to be a better LoRa messaging system than Meshtastic and welcome each integration as useful progress.
