Last month I got the CoolerMaster QuickFire Rapid with brown switches for $80, my first mechanical keyboard. Right after that, NPKC Front Printed PBT Keycaps just dropped on Massdrop for $30. I got the purple set. Two week ago I bought my first novelty keycap from KeyPop, the Lonely Panda for $3. Three days ago I bought 4 more novelty keycaps which totaled up to $18 (Saitama, Orange Gudetama, and Yellow Gudetama from Key Clack plus a LOD translucent keycap from Key Pop). Today Gem Artisan Keycaps dropped on Massdrop and I bought my first artisan keycap for $21. I chose the Amethyst to go with my purple keyset. I haven't included tax or shipping in any of these. There's my little story about how I started and I'm looking forward to the impending empty wallet.
Also, I'm planning to build my first keyboard next summer or whenever I get more money and time. The B.mini has been in my sights for a while. That underglow and 75% layout, gets me every time.
