I need a keyword tool, which one should I pick?
 

I need a good keyword tool, which one should I pick? I want lots and lots of keywords...

www.wordtracker.com
www.wordze.com
www.keyworddiscovery.com

I only know about these 3, is there any more good ones out there?

Another guy I know recommended keyworddiscovery for domain related keyword use, but wordtracker otherwise.

I am currently with WordTracker but it doesnt seem that accurate.

I use this one
