I have no knowledge of this plotter, and no connection with either of 
the companies I'm about to mention, but I am really very picky about the 
ball point pens I use so I thought I'd throw this out in case it might 
help someone.  For almost all purposes I use Pilot Precise V5 Extra Fine 
pens in black, blue or red; and I think they are just great.  For 
working crossword puzzles on newspaper stock, I've become addicted to 
the Pentel EnerGel 0.7mm pen.  This latter one might be too coarse for a 
plotter.  If I were going to try and devise a plotter pen replacement, 
I'm sure I'd start with the Pilot.  I do think they would need to be 
capped when not in use, and I don't know if that would disqualify them 
or not.
