cosmonaut is my favorite navi. I'd also suggest an original headwind, crosswind, or chronomat/blackbird. All of them have a really nice feel and capture the essence of their 1990-2000 era which were quite nice.
I've got a beautiful one that was just serviced for sale. I really am torn about selling it:
