If you want to really rock anatomy, or are very interested in it, then you should own both a netters and a rohen's. I found rohen to be a great adjunct to cadaver lab (fly through important structures a couple of days before practicals). Netter will provide you with the ground work to conceptualize writtent text into 3D structure, although somewhat exaggerated. Grant's is a bad ass as it really shows the much needed crucial anatomical relationships which are sorely lacking from netter (its hard to decipher what is truely important when confronted with many netter plates). I couldn't find the Azygous venous plexus shown well anywhere in netter, grant's had 2 pages on that sucker.
Of course all of these texts aren't worth much without the M&D text. I don't care how many times you blacked out secondary to ETOH intoxication.....that book will make you an excelent anatomist.
EDIT: M&D = Moore and Dailey.
