I have not thought about a price as of yet.  Only because I need to optimize the time it takes to make one.  I use a 4 axis Grizzly mini mill that I retrofitted to go all the cutting and engraving.  I enameled the compass engraving.  Next setup i will take some photos.
As for not taking pens on a plane these are the ones that WILL get taken if you carry them on board:
This is a cartridge pen that I have been working on the design for a while.  I am now "happy" with the clip which I make from a casing, Also it is a real pain to solder the clip to the top casing.  These brass casings are thin and not made of the best materials.  They tend to pit when heating them up.
