I don't understand what the appeal of this is. Why am I paying $150 for this? What does this keyboard offer that a well reviewed $100 keyboard doesn't?
It's a somewhat niche collectors item/hobby. You can order one and build it from the switches up. It's a cool looking keyboard and an opportunity to participate in a support program for a manufacturer you may or may not like.
There is a growing market for custom key caps and personally built keyboards right now.

I guess if I'm asking these sorts of questions then this keyboard isn't for me.
Its possible keyboard layouts may go rogue and some direction you don't like. Then you may want a custom keyboard for the layout you do like. (I prefer the ANSI layout myself.) If you're replacing a hard to find keyboard on a retro PC, you may want to go custom.
This one is a custom layout that sacrifices the Function keys, number pad, and a few other keys for the sake of a smaller footprint. For some uses, this would be great.
There are many reasons to want one, and many to not want one. No use investing in one if you don't know what you'd want in design or use. However, you never know in the future.
