As a former Bible translator in North Africa and a current pastor...I am both a commentary junkie and on a tight budget. I have WBC, NAC, NIGNT, BEC, NIVAC etc (and yes I know I am missing NICNT) What I am curious is...for those who have a similar library and the Zondervan Exegetical Commentary series...do you find that it adds substantial value? Or is it mostly duplicative? I know it is not a lot of money for the books involved, but at the same time it is enough money that I need to think about it because I really don't have very much margins in my budget right now.
