Does anybody know any keyword tools? I would prefer the free ones.

Google has an awesome keyword tool that is by adwords, so I would look into that. I don't know of any off the top of my head, but you could probably Google search and find a ton of good keyword researchers, keyword generators, etc. There's probably a lot of them out there.
