SAT prep book help

<p>I am looking for the most comprehensive sat prep book that caters to a strong math review. I need a huge amount of help on math, and want to find a book that gives indepth reviews and analysis on math problems. Iam already going to buy the official college board book, but iam stuck between choosing Kaplan 2400, and Barrons 2400. Which book do you think is the better for a stronger math review? I have Princeton Review Sat, but its not enough on what iam looking for. Thanks for the help</p>

<p>Gruber's is supposed to be great for math.</p>
