Best GMAT study material

[callmemike20]

So, I'm graduating with a degree in finance in May, and I was going to take the GMAT a few months later (I don't plan on attending school until I have a few years of work experience). Does anyone know of any good study material?

EDIT: I'm aiming for a 690+

I used the Manhattan GMAT materials - very good and very comprehensive. I was able to improve my score about 90 points over about two months of studying. The materials are somewhat pricey if you compare them to just a Princeton Review book or something of that nature, but IMO they are significantly better.
