The 200 has different nozzles and needles. I think they normally come with the medium in them, I know mine did. To do find lines you may need to get the fine nozzle and needle.
Keep in mind that most of the ability of an airbrush comes from the painter not the brush itself. They take a LOT of practice to get good with, so since this is your first don't be too surprised if it won't do as well as you think it should at first. Be prepared to spend some time getting accustomed to it and learning how to use it. Fine lines don't happen right out of the box, they take some practice. One of these days I might even be able to do them well
