I'm a pen whore.
I know that by posting about a pen, I'm taking a risk in outing myself as a real geek. But then I realized, I'm practicing patent law in a few months, so I'm not fooling anybody at this point.
I've managed to keep my pen addiction to a minimum for the last 7 years. I don't lose my pens very often, so I've been able to use the same core set of pens since high school. And because I have used a laptop to take my notes, I haven't felt the need to take too many notes by hand.
But during my preparation for the CA Bar Exam, I find myself having to handwrite a lot of notes. So when I finished my last exam, I treated myself to a minor shopping spree at Office Depot. I found a decent Cross ballpoint pen, and on my way out of the aisle I took a risk and picked up uni-ball's 207 Premier, priced at a mere $4.50. I didn't have the highest hopes, but what the hell.
Seriously, go buy this pen.
The medium (0.7mm) ink throws out an ample amount of gel ink, which is acid-free, and fade- and water-resistant. I did try a bold (1.0mm) refill and I don't recommend it unless you're about to sign the Declaration of Independence; and even then someone else is likely to ask who the jerk is that used that really inky pen.

This pen is on the light side, but remains well balanced. Unlike these uber expensive pens that are always top heavy, a little blurry, and therefore more difficult to control, the 207 Premier is even-keeled, sharp, and agile. It has a decent squishy grip that is contoured, but the pen overall doesn't suffer from that pandemic "Dr. Grip"-bloat. This isn't the size of a magic marker.
This pen isn't flashy, but its a joy to write with.
