Yes, I have used Micron and Zig Millennium. The Pitt pens are not so useful on their own as they have a brush tip which is useful for solid shading.
Ink bottles were also used to dip the tip of the brade of the girl sitting in from of you in school. Not that I could ... I was always sitting in the front row, or standing in the corner.
You will eventually want to purchase indigo ink and a mapping pen by speedball. Part of the pen and ink training is in proper use and techniques of the traditional tools. There are several lessons on pb where you use micron and dip pens together to achieve desired results. I love my mapping and dip pens now. I use them whenever I can. Inking is an art. Some people will also use a very fine tipped brush when inking. There is value in learning how the ink flows and can be manipulated with different pen nibs, brushes and dilution. For most of the lessons however, a micron will work but you will run out of ink quick. I am a pen doodle freak and use a load of ink and go through pens very fast. My dip ink pens last for years. Check out my pen and ink butterflies on my gallery to see what I mean by ink manipulation.
