For more than 20 years, the EBC has been widely recognized by preachers, teachers, and laypeople as one of the best commentaries available. Each Bible book features an insightful introduction, detailed outline, penetrating theological and critical exposition, and useful bibliography. Notes on textual difficulties are kept separate and all Hebrew and Greek is transliterated. Esteemed evangelical contributors include Walter Kaiser on Exodus, D.A. Carson on Matthew, Merrill C. Tenney on John, Richard Longenecker on Acts, James Montgomery Boice on Galatians, and Ralph Earle on 1 & 2 Timothy. An excellent resource.
If you are an evangelical looking for one affordable full-Bible commentary, this is the one I would get. If you are in a more moderate or liberal tradition get the New Interpreter's Bible. If you want to be a well-balanced fair-minded teacher and preacher, get them both.
