Rapidograph technical pens are pricey little buggers that can be intimidating for the uninitiated. I'm not claiming I'm not intimidated or uninitiated, but I've got a couple of Rapidograph pens in my growing overpriced pen collection, and I thought I'd share the little I know.
1. I am AWARE of two brands currently producing Rapidograph tech pens- Koh-I-Noor and Rotring. There may be more brands, I just haven't encountered them. Within these two brands, I know that Koh-I-Noor Rapido-Sketch pens are different from their Rapidograph tech pens. I bought the Rapido-Sketch pen a couple years ago because it was on super sale and I wanted to test it out (having heard good things about Rapido-Graphs), but I've never been able to get it to work.

The Rotring comes with a prefilled cart, but the nib is not assembled (its in the plastic casing to the right of the Rotring cart), so there probably isn't much ink choice. The Koh-I-Noor is filled by the user, and the ink container is fairly small. Depending on where you buy your Rapidographs, you can pay anywhere from 14$ to 29$, and some of the Koh-i-Noor sizes are on backorder.
