I have multiple articles of clothing that cost more than that. I’m baffled as to why anyone would want a keyboard that costs more than $100. To each his own.
Around $200 and above, most are machined from aluminum, and require the user to supply their own switches and keycaps. My daily driver, whose USB connector seems to be reaching EOL, is a heavy-ass chunk of bright blue Alu, makes noise like a machine gun when I need to correct someone on the internet, and has limited edition keycaps in a fun (imo) purple-and-cyan color scheme. Total cost of this thing was probably $250~$300, but I'm happy.
I have over $1k worth of keyboards and related hardware strewn about my apartment, and the only reason I've considered selling some of my collection is to buy fancier pieces. To each their own.
