Today's fountain pens from the middle price segment technically all write at a comparably high level, which is why the decision strongly depends on subjective factors like ink flow, nib width, feel and look. Manufacturers like Lamy, Pelikan and Graf von Faber-Castell offer very good workmanship as well as reliable service. It is recommended to try out the models oneself before purchase and to bring one's own everyday paper in order to check the ink flow and nib width realistically. Ultimately, gut feeling decides, since with none of these models can one go significantly wrong.
