Which type of pen/nib do you recommend me for drawing manga?

I'm starting in the world of manga, and I've read that one cheap and effective way for inking manga is to use pens/nibs. There are lots of them, in all kinds of sizes and prices, and I can't decide. I'm needing a pen that makes fine lines (as far as I know a 0.1), another one to make broader lines (0.6), and a marker pen to fill zones with black. I can start with something cheap; in fact, I *MUST* start with something cheap. Any help?
