The thing i like best about ZSA, is that they are selling products. Just buy, configure with a nice web tool. No soldering, assembly or programming required to make it work.
All other Ergodox, or Ergodox alternatives, seem like much more work to get working the way you want.
Anyway, the thumb clusters were my primary annoyance with my Ergodox, so i ordered a Moonlander. I hope it works out.
