GMAT Strategy

Ive been lurking around for a while now and read through some threads.
Im trying to purchase some books to begin my studies but im having some confusion on what to buy.

From the wiki suggested books link, I see Ill need the "OG" books, and either a Kaplan or Princeton review book. Ive read a lot of opinions for each book. Some say Kaplan questions are harder, some say Princeton is close to the real thing. Which book(s) are recommended for a complete Noob?

Thanks
