This book does not deal with analysis, it is a book of the texts of the ancients. The textual translations are accurate, and the sources Allen provides for further research are sound. It is an inexpensive quality way to learn the extant writings of the Ancients. If you are looking for analysis or explanation, though -- look elsewhere.

For a teacher willing to present his or her own analysis of the period, but looking for an inexpensive source of well-translated key texts from the pre-Socratics to Aristotle, this collection is unbeatable. At 450 pages it contains more than enough core reading for a one-term course. Moreover, it includes the 'unmoved mover' argument from the 'Phaedrus', which its competitors, even at twice the length and thrice the price do not.
