Thanks lukus! That Fisher Stowaway seems like a great, inexpensive way to try out the Fisher.

Actually, looking at Fisher's website, I now realize that Fisher makes a whole slew of "space pens" and not just the rounded, silver bullet style. And they make universal and brand-specific refills for other company's pens, too, so it's possible that I could turn my favorite pen into a Space Pen with just a refill change. Boy, I wish I knew this a long time ago!
