Better Resource: Eat This, Not That: Supermarket Survival Gu

Options
If you have one of both of these books please suggest which is a better overall value. I have the Eat This, Not That guide from either 2010 or 2011 but know that some of the information is outdated. Is the new edition updated enough to warrant buying another copy? Also are the recommendations in the Eat This, Not That: Supermarket Survival Guide easy enough to locate at your local supermarket. I know that some of the supermarket recommendations in the back of the Eat This, Not That guide that I have are very difficult to find.

If you know of any other good low calorie recipe books or books similar to Eat This, Not That please feel free to recommend...Thanks!
