I like the Filco ninja keys, as although I touch type pretty fast, when I'm tired I still hunt for the rarer keys like ^|¬
Ninja/blank keys are just to wind up wife/daughter if they try and use it. I never have to look at the keys, even the obscure ones, once I'm used to the keyboard. I'm coding a lot of the time so I do use pretty much every symbol at some point in a day (or in one or two lines if writing perl). Haven't checked typing speed for years but last time I did was somewhere around 140wpm.
The most common non custom keyboards with blank keycaps are HHKB, Filco Ninja and Das Keyboard.
Das Keyboard is full size, HHKB is too small, Filco Ninja tenkeyless is difficult to find in stock.
Also no media keys.
