SAT Critical Reading and Writing Prep Books?

<p>I am about to order Direct Hits 1&2 and I'm looking for one or two more books that focuses on CR and writing (grammar). Any recommendations (I already own College Board's SAT prep)? Also, I've already skimmed/looked through SilverTurtle's guild and the stickied thread for SAT prep books and I'm still not sure which ones are best.</p>

<p>Although I have not personally used it, many praise Grammatix as being good for CR.</p>
