My journey so far has been (24yo):
The keyboard on my dads HP laptop
Generic keyboard that came with my familys first home computer (WinXP)
A Logitech Ergo version who knows
Logitech G110
Logitech G15
Razer Arctosa
Razer Blackwidow 2013 (first mechanical)
Misc. Tesoro brand keyboard
Mistel Barocco MD600 (split)
ROG Claymore (removable and sideswappable numpad)
Keychron K3v2 <- now
Next might be a printed -dactyl or moonlander.
