I'm new around here, so my input may be insta-ditch, but some thoughts:
1. Vimcaps are super-popular, right? I understand that it's not quiiiite “true to the original board”, but what about moving the double-arrow on L to G, and then arranging the arrows on HJKL, vim-style? Saves quite a few of us an extra group-buy, later — and shouldn't bother the non-vimmers, 'cause it's not like the legends are meaningful to anyone else! ('cept the two APL users reading this thread …
2. Personally? I'd instantly pay $80 for the Colevrak set, if there were only like ten other people who'd be interested in it. Hell — I'd drop a couple hundred, paying for a few of those moulds
myself. It's really hard to find sculpted caps with Colevrak support; and Space Cadet is a lot of developer-keeb-nerds' #1 endgame. This leaves people like me having to choose between … A. a non-sculpted layout, … B. keycaps that disagree with the actual layout (fine for us touch-typers, but sucks for pairing / family who want to use your machine), … or C. using whichever of the two(?) colorways that *do* have sculpted Colemak caps floating around out there you hate less.
Maybe I don't understand how MOQs work … but why not just offer it at a higher price, for us needy niche nerds, if you're worried too few people will be interested?
