sorry im trying to figure out the jargon here. you bought a mechanical keyboard and then replaces the keys (ABS with PBT) ? is there anything that has this off-the-shelf ?
I'm very new to mechanical keyboards, but I just got an Epomaker EP84. PBT keycaps, and hot-swappable switches (I got brown). Very happy with it, though I've not tried any others. $85 (though I'm in UK, it was £70 here).
