Welcome to Geekhack!
It gets bad, very bad indeed!
Bad like $500+ for a single artisan keycap!
Bad like buying 5 or more HHKBs!
Bad like having at least 4 keyboards for each of your computers, and at least 4 keycap sets for each of those keyboards!
Mind you, there's threads like
this one that try to provide a little balance.
Good luck! Resistance is futile
