 a very good job on them. They're still...membrane keypads, though. Eeew. 
 There are companies ("Fourth" came to mind, I used their products many
 times) that produces real keyboards (beyond membrane and chiclet ones)
 in Brazil. 
 
   They produce them to spec?  I wonder if they can do small quantities.
   Another option might be those keyswitches that have transparent
keycaps, under which you can stick labels.
   Of course I adore those keyswitches that have a tiny color OLED
display in them.  At $50+/ea that'd make a pretty expensive calculator
though.
