Update: these are out-of-stock! Cross.com has their Ion Pen Value Set marked down from $50 to $12.50, 75% off the standard price and the best deal I've seen. Plus, enter coupon code SPRING08 to get free shipping with any order through 3/18. For reference, one Ion pen is $23 at Staples! The futuristic Ion pen is refillable in 6 colors, is ergonomic with a one-hand open/close operation and has an "elliptical translucent window that displays the ink level."
