I just found the 2nd ed Essence of Anesthesia and snatched it up!! I am not sure yet if I made a mistake or not, but I have heard so many good things about it and have been on the lookout for it a while now. Any input?? Is it worth the money?? Not sure if I should say how much I paid because you guys will laugh at me......it wasn't too bad. It was not the highest price or the lowest.
