Try a quick-drying ink from Noodler's, such as Bernake Blue or Bernake Black. I'm a big fan of the Platinum Preppy with an o-ring to seal the whole body allowing you to fill it with ink—it's dirt cheap and writes very well. I recently picked up a Pilot Metropolitan, slightly more money but again, impressive value and it comes with a converter (which is like a cartridge that lets you refill with your own ink).
