What would be the cheapest way to get a hot-swappable wireless standard bottom row 96%/1800 decent/ish ANSI keyboard that charges through type C (with Akko V3 Cream Blue Pro)?
my initial plan was to get an Ajazz K992 and buy the switches separately but it seems the bottom row is non standard so getting keycaps for it would be harder
Ah no, part of why 1800 boards get to be compact is in the squishing of that area. The good news is that it's pretty much shared with 75% boards, so while not universal, a lot of keycap sets will also have 1u modifiers just for that.
