What about GH60? Mine is pretty much HHKB layout with a little twist (extra right CTRL and extra left FN). Check out the picture:
BTW it's got PCB mounted 62G Zealios, blank black enjoy PBT caps in cherry profile and just bare standard plastic case.
In fact I like it more than HHKB for traveling, because it's quite a bit lighter and it works just fine with iPad (HHKB doesn't).
Also because it's fully programmable I can switch between Windows/Linux and Mac configurations with a FN + FN + ESC
Oh and it has firmware based mouse keys
Didn't mean to advertise my hobby company (FalbaTech) but you can get an official GH60 (always latest revision) from us at decent price and not deal with all problems you get from Satan GH60 spinoff.
