I'd venture to guess that most "pen people" have experienced some variation of the Jetstream at this point, but you may not have tried the relatively new 'BLX' model that features ink that is a blend of black with colors like red, purple, and green.
It's difficult to capture the subtle green component, at least with my proficiency using a camera but, even in person, the exact color is a bit elusive. My fiancee thought that the color might have been a dark blue with hints of grey, but I thought it was a definitely a green component, though it looks blue black in the sample.
The overall construction of the pen is excellent for the money. Everything feels solid and long-lasting. I like how the plastic near the top is tinted to an approximation of the ink color. The whole package is professional, modern, and well executed.
The grip area is basic, yet effective, and the barrel shape doesn't restrict how you hold the pen short of the clip occasionally getting in the way.
