Just dove down this rabbit hole myself yesterday. I decided I wanted to be up and running with my Meshtastic device sooner than later and with little headache, so I went and got myself a RAKwireless WisMesh Pocket v2 that was pre-assembled. (Bought from Rokland, if you're in the US.) I decided to go with it as it has an OLED screen, GPS radio, rechargeable battery , and an external antenna with bluetooth. Possibly more than I'd ever need, but I'm excited to get it and try it out.
