I haven't seen anyone mention the
Code keyboards yet. I purchased one for work with Brown Cherry keys and I am oh-so-very happy with it. The next nice keyboard I get will probably use either green or blue Cherries, since I tend sometimes to bang away at the keyboard when I get going.
Also, FWIW, I use a
Unicomp buckling-spring keyboard at home, and I am thoroughly unapologetic about the clacking sounds I make when I use it. From my experience (and I have used many different keyboards), heavy mechanical keyboards are the best kinds to get. Beyond that, the switches are something each person needs to explore and decide upon. I am a fan of hard-to-press, clicky switches (even though the browns don't resist my hammering much at all), which is why I use buckling-spring at home.
