JT Keycaps JTK MX Sliders for Topre

Yeah, I just had the spacebar printed and it set me back $50. But I justify it as "I don't want to wait an indeterminate amount of time for someone to sell me a novatouch spacebar and it annoys me enough to spend $50 on it"

because a set will cost you about $400?
