Got to say it’s interesting to read this comment and check the site and prices are 150~600 (the upper end being an anniversary edition aluminium and stainless beast).

Obviously really expensive for what is at the core a spring and an electric contact or two (depending on type) — which can be just one part at the expense of longevity, but as hobby pieces it seems quite reasonable, I’ve seen way worse spends from friends who fell in love with mechanical keyboards.
