I have used many tools, but the obvious one is the original free google keywords tool. Notice that it rounds up values, and they are usually double the organic search value, because they include keywords searched on affiliate networks. There is also some lag in their reporting, but if you pick your country, language and the EXACT searches number, close enough is good enough. They also give an indication of competition for the words, but you can probably guess that from the kind of sites that rank highest for that word. at the end of day its often the long tail (combination of words) that bring most traffic to your site anyway, so just keep writing around your top keywords and keep it fresh.
Google Keyword Suggestion Tool could help you. You could also do Keyword Analysis by analyzing keywords related to your site, and what your competitors used in their websites..

Most keyword tools take data from the google keyword tool. Market Samurai was my favourite, but it no longer works since the last update of the google keyword tool. The best free tool is certainly google's keyword tool.
The best way to get good keywords is to get words about your site like for example your genre or what you website is about.
