I've been searching various online bookstores (amazon, BN, Borders) but have not found a book specifically targeted at the 70-621.
Any suggestions on where to find such a book, if it exists?
I suppose the alternative would be to study for both 620 and 622, but that seems like overkill.
Also, are the Exam Cram books considered "brain ****" or something to stay away from?
I see a listing for a book that is not yet out, and it covers 620, 622, 623:
