Gotta love how the Cherry Mx design went into pd and now all of a sudden, we get full 101 key boards with mx key switches!
I have a number of mechanicals... I find that I prefer cherry white or red for work, cherry blue or an old IBM Model M.
I bought most of my boards on the cheap watching ebay auctions. My current work key lard is a cherry g80 with a credit card swipe. Huge, but I don't mind. I do prefer not to have lights on my boards, however... They're just distracting.
If any of you guys ever go back in for an old IBM Model M spring switch boards, they're usable with modern computers that support ps/2 protocol. Otherwise, there are replacement SDL cables that you can purchase for about $40 that allow it to speak USB. Or you might luck up and find one of the "blue cube" adapters from 200x in the parts bin at your local electronics store.
Bolt mods are also fun stuff for those old ibm boards. I can't feel the difference, but I will say that it basically future proofs my board for another 30 years. And allowed me to save more than one of them that had cracking plastic that would have died a quick death otherwise.
