As seen above, there are people who are doing nicely using Adwords, and others well... not so good. If you use Google Adwords KEYWORD TOOL you can do research on the keywords you're interested in. It'll at least give you an idea what kind of competition you'll experience.
To not give it a shot is, IMO, a mistake. I think Adwords even gives you $25 to start out with so why not at least test it? Just be sure to set a max "budget" else you could end up with a large bill at the end of the month.
