Microeconomics - Study Guide

I have used Parkin as an auxilliary source for my micro 102 classes for years. His examples are products that can be related to by 19-year-olds, AND he does not use wheat or other perfectly competitive products to exemplify a downward sloping demand curve! Many other do, which causes great confusion among the students. What is wrong with careful, thoughtful, comprehensive explanations of concepts that are difficult for first time micro students? He covers several complicated topics that are left out of the more highly rated texts by Mankiw and others. I am wondering if we are even rating the same book...I give it the maximum rating!
