I'm trying to find some prep books that have a fair amount of detail, since I'm not on a crash study plan. I don't want a deluge of info, but something more than basic review would be great. I'm wondering which prep company's books provide this. I've heard mixed opinions about Berkeley Review's books, and I was hoping to get some more opinions about them before I invest all that money in their books. I'm not really interested in classes since I learn better on my own.
