Speaking of which ... for the last year, I've been using a combination of these two for my daily note-taking. I'm extremely delighted with them (especially the nib):

- Waterman Hémisphère fine nib pen[+]. It costs between 80-105 euros, depending on where you buy.

- Waterman "Encre Noir Intense" (Intense Black Ink)
