A Buchanan has a huge range of New Testament commentaries; including.

Gospel of Mark: A Commentary - Moloney

Francis J. Moloney, S.D.B., professor of New Testament and recently appointed Dean of the School of Theology and Religious Studies at The Catholic University of America in Washington D.C., has completed what will be for many a useful resource for understanding Mark's Gospel. Moloney's exegetical concern is to "trace literary and theological connections across the Gospel" (p. 21). These literary and theological threads point to a reading of the Gospel that encourages its reader (whether first century or twenty-first century) to "hope in the midst of ambiguity and failure" (p. 24).

Gospel of John: A Commentary - Keener

"Sixteen hundred pages is a lot of pages for a commentary on the Gospel of John, surpassing Raymond Brown and almost matching Rudolf Schnackenburg’s three volumes. But Craig Keener has given us far more than a commentary. He has invited us into the world of that Gospel and made it a magnificent window into the thought and practice of early Judaism and, to a lesser extent, the whole Greco-Roman world of the first century. At the same time, he has made those first-century worlds a lens through which to view the Gospel of John itself. The reader will find this work a treasure trove of information about the origins of Christianity, shedding light on such questions as what is a Gospel? how reliable are the four Gospels in their portrayal of Jesus of Nazareth? and in particular how reliable is the Gospel of John? Keener presents a compelling case for viewing Jesus himself within the framework of early Judaism, and for both the Jewishness and the essential reliability of the traditions about Jesus preserved in John’s Gospel. Keener’s introduction runs to well over three hundred pages, and his bibliography to almost two hundred.

"The book is a remarkable achievement, and all who work on early Christianity in general or on John’s Gospel in particular, whether they agree with Keener or not, will have to pay attention both to his facts and to his argumentation. In that sense, it is something of a milestone, not only in Johannine studies but also in the scholarly world’s ongoing investigation of Christian origins."
