I like Preppies. I don't know where to get them for $4 (open to suggestions), but I often want to try exotic inks with some pigment or sparkle or acrylic or acid (iron gall ink) or whatever that risks damaging a fountain pen. I'm fine if I neglect to clean it and it clogs the Preppy. Oops. Throw it away.
