Of the classics it would be the HP-21 for the same reasons. A clean black, white and blue keyboard below a red-glowing display in a cute little package.

If you like the HP-20b:


and the HP-21:


What do you think about the HP-10C:


and the HP-22S:


Even the HP-42S isn't much cluttered:


Kind regards
