Not only is BNTC an affordable NT commentary set, but it is a great one. I had the honor of taking a class with Kistemaker on the book of Hebrews and I loved every minute of it. His commentary reads much like his class. One feature I really like about BNTC is that it is very approachable for the non-scholar, but it also has sections addressing issues with the original language for those who want more depth from their commentary. It is almost like 2/3 "popular" and 1/3 "technical" in its approach. Great addition to your library.
