Get the Princeton Review. It helped me out a lot when I took the GRW a few years ago. I got great scores. They focus on the things that you can do that will best help increase your scores. For instance, the best predictor of a high score on the written section is length. There's other useful information of course, but keeping things like that in mind is very helpful.

Avoid the "official" the study guides from ETS. Some people think that must be the best study guide because it comes from the people who make the test. That's not true. Remember, they have an image to maintain. They are selling themselves to universities as an "objective" test of intelligence, and future academic potential, which is utter nonsense. The GRE only tests how well you take the test, but you have to get through it if you want to go to grad school. Thus, ETS claims to those who get the results of the tests, but not to the ones taking the test, that the scores are a "reliable" measure of intelligence. Which means that no one should be able to study for a few months and dramatically improve their scores. Of course you can do that, but their material will not be as helpful because they solely focus on examples of past GREs, not strategies that increase the probability of a better score. Princeton Review is all I used and I was very happy with my scores. Now I'm finishing my third year in grad school.
