Helpful companion if you want to learn more about the Pilot pen featured in the article: https://unsharpen.com/pilot-precise-and-hi-tecpoint-pen-guid...
I don't have tremendous disposable income but pens are a pretty minor indulgence, which might excuse making them into a fetish item, writing pointlessly elaborate reviews of them (https://jakeseliger.com/2009/04/05/product-review-pens/), and so forth. Overall, I've come to like the Pigma Micron PN ("plastic nib") pens, which writes smoothly and from any angle—including above my head, which is handy for someone who likes to lie down and read.
I've carried around fountain pens, but they are too expensive if (when) lost, and too finicky.
