Background: I travel a lot, and write professionally. (When the local stationery store sees me walk in, they start stacking bottles of ink on the counter.) My go-to instrument has therefore been the Pilot V-Pen, a brilliantly smooth-writing disposable fountain pen that holds enough ink to last even me for a while. However, it has one flaw: refilling it is a pain in the derriere. You need two syringes, which always makes me feel like the pen addiction has crossed some kind of line. (When a girl sees empty syringes on your nightstand, pen refilling isn't what comes to mind.) Therefore, my quest for a replacement. What I'm looking for: A pen that's... Cheap, so I can buy a couple and knock 'em around.Widely available, or at least can be easily mail-ordered in Asia.Writes astonishingly smoothly. Trust me, when you're putting industrial quantities of ink to paper, you want it to be easy.Has an ink capacity measured in liters, or at least feels that way. This almost certainly means no converters... since they take up space that could be used for holding ink!
