I'd think anybody who wants one with an 18K nib would probably also want to wait for gold tone furniture on the rest of the pen, which I understand to be a possible future project. I think there may also be a titanium colored finish that has been mentioned as being possible.
As to why an 18K nib, why do some people (including me
) want a bulb filler? Steel is a perfectly functional material, and 14K may offer more benefits than 18K does. 18K appeals to some people, and I think it is probably not just snob appeal. There are a lot of good pens that opt for a 18K nib, and I think some people associate them rightly with that level of quality. I personally would pay more for a good palladium-based nib, but that's because I love the way my PdAg Snorkels and my palladium 8xxx Esterbrook nib writes.
Gold does offer superior properties for anybody considering filling this pen with iron gall ink...
