The Big 5: Commentaries on the Gospels/Acts

Here's a different approach.  What are your big 5 commentaries on the four Gospels and Acts?  I want your #1 commentary for each book: Matthew, Mark, Luke, John, Acts.  That will be a total of 5 books.  If you could only have one on each book, which would it be?  What's the first one a seminary student should have on his shelf?  Go!
