Foundations of the Market Price System
Murray Rothbard just loved this Austrian text on microeconomic theory. In fact, he thought it was the best text available — except that it has only been sporadically available since it was first published in 1974. It is characterized by a strong pedagogical drive, a logical precision, and an excellent presentation that competes directly with mainstream alternatives except that this one follows Rothbardian logic. The typesetting is from a typewriter, which is unfortunate, but it is nonetheless very clear, as are the graphical expositions. This reprint preserves the original.
