lol, I just realized why the Flint 2 was being offered with such a big discount!

Oh well. Today the Flint 2 costs the same as the OpenWrt One, but came with free overnight FedEx shipping vs. paying $20+ shipping that would take weeks to arrive. It should do everything I need for now.
I'll be back in two years with a Flint 3 vs OpenWrt Two question!
