I have a drawing tablet which I use frequently with pixlr.com/editor (great for drawing, check it out!) and I doodle there a lot. But for real-life drawing I've got a bunch of drawing pencils ranging anywhere from 2B to who knows. And I'm not sure if you care, but there's these watercolor pencils that you draw or color with, then add water to it and it looks amazing! I do tattoos with sharpie on my friends a lot, too.
