For anyone interested in The Inka Pen, I found a review: Inka Pen Review

Thought I'd pass it along.

Hey, I didn't realize they had a stainless steel model for $25 - that's more reasonable - there's no way I'm paying $90 mentioned in the other threads on this pen, for the 4 grams lighter titanium model.

Does anyone know if it takes a standard size of pressurized ink cartridges or are they proprietary?

To partially respond to my own question - I wonder if the Fisher Space Pen "Universal Refills" would fit? In the picture they look like they have two breakaway segments to fit shorter pens...

They accept standard Fisher Space Pen refills.

I was just reading through the March 2006 "Adventure" magazine (by National Geographic) and there in the back, in the ads on page 99, was something similar.

The "Trekker" by Fisher Space Pen is shown. Looks very close to the Inka Pen. A trip to the Fisher web page didn't turn up any Trekker pens. Perhaps this is a new product...
