Thanks to Nevermore for starting this poll! We've contacted the vendor on your behalf and they've made the XD75 Custom Mechanical Keyboard Kit available.
Has there ever been an Atomic drop? I have some cherry clears to use up that I did not use with my Ergodox so I would like to get an ortho kit as there is no way I can go back to staggered keys after the Ergodox.
In the end I bought the Atomic PCB direct, I have just received the Overcast keys so it is looking quite nice. I just have to decide on the keymap that makes the Atomic layout as close to my Ergodox layout as possible.
