I really like Saunder's NCLEX review. The book presents the information in a nice summary format, and the companion CD has loads of questions with detailed rationales. If you prefer to do questions in a book, rather than on the computer, then don't get this one because the book itself doesn't have many questions.
If you do some googling, you can find many NCLEX books in PDF format and CD programs for free. These aren't technically legal copies, but if you just want to screen them to see what you'd want to buy, do some searching
