The Pilot Vanishing Point doesn't need a cap, the nib is exposed and protected in a manner akin to clicking a ball point in and out. Mine works perfectly.
The Lamy 2000 is sleek and modern looking with a sophisticated design. It looks like a fountain pen that one might see in a Star Trek movie, but this model has been around since the mid 1960's. After half a century, the design is still the favorite of my collection. It operates flawlessly.
I own the other, less expensive fountain pens mentioned as well; they would be good choices too. I started out with some of these and I still like them, but it is easy to get hooked on buying more fountain pens and fancy inks.
