I'm sure many of us on the forums have more commentaries than we may ever have time to consult. (Maybe you do refer to them all. I certainly don't.) Therefore, I try to be very selective when making additional commentary purchases. In addition to Carson's book on NT commentaries, I tend to also consult the Denver Seminary recommendations which are updated every year. I've just noticed that Keith Mathison has started to update his top 5 on every book too. He hasn't completed the update yet, so there's no official landing page, but this link should take you to a page that shows his posts so far.

Does anyone else have recommendations on choosing wisely? Obviously the Faithlife 30 day returns policy helps to some extent too.
