I see on Drop that the Tokyo 60 keyboard is rarely available. There is something in kit-packaging but not in black as I would love it. I love the HHKB layout to the point that I am configuring my ALT keyboard and my Hexgear Gemini as close as possible to it. But I struggle with keycaps due to the "backspace" and "|" swaps that the keycap sets on drop do not support. Why is Tokyo60 so rare on drop? What are the alternatives to it?
