I heard about Spyfu when I started out in internet marketing but I have lost track of it. Can it be use for keyword research and analysis? Just like Traffic Travis and Market Samurai.

Yes, but that is saying it mildly. You're getting much, much more with Spyfu. You'll know exactly where and what they are advertising. It's a little pricey if you're just starting out, but they do have free access if you want to try it out.
