Now, they are or have already released a value edition with a thinner pcb and comes in more switch options, so build quality might be a bit different than mine. But it's not like they're impossible to do stem swaps in to get clicky switches
http://kbtalkingusa.com/pre-order-keyboards/I'll do point by point commentary:
Single layer/sided PCB. There are durability issues with Single layer PCB. I am surprised Yeager approved this.
Unpainted case. Unpainted cases are usually ugly. I'll keep an open mind about this, but I am not optimistic. Most keyboard you see on the market are painted, only exception I am aware is Realforce. I may talk trash about Realfarce, but their case really do not need the paint to hide the ugliness (of course I still have to point out for 300 dollars, you still get a warped case). But I digress...
No UV coating on the keycaps. There was an original version in the Taiwanese groupbuy that came without UV coating. Only 1 batch of these "value edition" were made. They went for 3999NTD I believe.
No R5... Trust me, you don't want the R5... R4 is fine.
They have wire stabilizers (aka Costar). I'll have to ask who this is built by. I suspect it is built by the same factory as before.
No aluminum name plate on the back.
No fancy manual that folds into a calender. Ierno. No care.
