The following is a quick guide to all the materials I use in inking.
Felt Tip Pens
Felt tip pens are some of the most common inking tools out there. They do a good job, don't cost too much and are pretty easy to control. With a felt tip pen you want something of good quality and probably something waterproof (if you're using non-waterproof ink make sure you color only copies of the image). Micron is probably the most popular brand in America and while these are great pens I've found I wear out the 005 size pretty quickly - not that it runs out of ink, but the tip of it just isn't that strong. Still, Microns are a good place to start. My three favorite brands of felt tip pen are Copic, Pigment Liner, and Faber Castell (note that of these only copic makes the 005 size!). Microns and Pigment Liners can be found at most art or office stores. You might have to special order or order online if you want a set of Copic Pens, but they are very reasonably priced and last a long time. Some people also use Sharpies - be aware that marker tends to make them bleed so again, only color copies!
Brush Pens
Brush pens are usually a type of felt tip pen too, but shaped like a brush. They take some practice but are well worth it. Again I suggest the Copic or Faber Castell Brand (the Micron ones are not that good).
Ball Point Pens
Most inking you want to do with a waterproof pen, however you can get some interesting effects if you use ball point pen. I personally like the "Zebra" brand. Again make sure you only color copies if you're using non-waterproof ink.
Gel Pens
Most Gel pens do not come in small sizes or with waterproof ink - except for Hi-Tec-C pens. Hi-Tec-C pens are a fine point gel pen made by Pilot - sadly only outside the US. I haven't found a way to order them online so unless you live near a Japantown or Little Tokyo (or know someone who does) it's pretty hard to get them. They work REALLY well for doing fine lines though! A 005 Micron pen or Copic pen will also work, but it's a little harder to keep them making an even line once they get a bit of use.
Crow Quill Pens
"Crow Quill" pens are actually named after Crow Quills (feathers). These days they are made from plastic and metal with no actual feathers involved! This is the type of pen you have to dip into ink to draw with. While they can be rather hard to use they can create some really nice results! I suggest Speedball and/or Hunt Brands.
Brushes
Inking with brushes is very hard to master, but really worth it (needless to say I haven't mastered it yet). Even if you decide not to ink with them for the most part it's a good idea to keep a tiny brush around for adding in white highlights, correcting mistakes, filling large areas etc.
Inks
For separate inks to use with Crow Quills or a brush I use three brands: Higgins makes nice drawing ink in all kinds of colors as well as a great "Eternal" black ink which I love best for drawing with crow quills. Copic makes an "Opaque White" very thick ink/paint which is great for adding highlights and correcting mistakes etc. Lastly, FW makes a line of Acrylic Inks which are nice for doing really solid colors.
Papers
For most inking I use either marker paper or regular office/copier paper. For working with a crow quill pen I like Aquabee Pen & Ink Sketcher paper or Bordon & Riley Bleedproof Paper for Pens.
