If you like to have variety in color and tip sizes, you can probably find a Sakura Pigma Micron that fits your preferences. I love these pens, and I think everyone should try them, especially if you want ink that is archival quality and waterproof/fade proof. The tip on this .25mm model has a very small tip, but it seems to handle my abuse pretty well. The clip is small, yet functional. The barrel is nice and slim and, though there is no grip, the pen is comfortable to hold. This is pretty comparable to the Copic line of pens, and both are fantastic. At $2.25 a piece (JetPens), these are great for the money. Go get one.
