here is, the famous 12c.
famous because it is still successful after years of production (there
is a now new production 12cp replacement).
you can see why. as a finance calculator it is small and convenient to
carry. the sideways voyager design has style and the display is
clear. furthermore, it has a reputation for getting the right answer,
which is important for a business machine.
the keyboard layout is good too. uncluttered with stuff you don't want
in such a machine.
other financial models like the 17bii
and 19bii are also excellent but somehow lack
the style and accessibility of the 12c. the gold trim looks smart too,
providing you dont scratch your name on it.
