I have reviewed both books and you may want to read the reviews in the "Book Reviews" forum. In general I found Allen & Bambara cover more ground than Cade's book. You will find detailed coverage, some very good examples and a lot of test-oriented tips in Bambara book. It also comes with a CD containing two full length exams with an option to download one more from the publisher's website. The case study intended for the assignment(part II ) of the test is well covered in Cade's book. The assignment part covered in Bambara's book lacks the depth required( and expected by Sun ) for the second part.
