I own the NKJV edition (2001), and plan on getting another copy in the just-published ESV edition also. It is, quite simply, the best study Bible I have ever owned. The format is excellent, there is ample margin space to make notes in, and the study helps are incredible. You can get the ESV in hardback, shipped, for under $30 (the NKJV was $60 in HB, and even more in leather).
It seems to me to be the most concise and direct Reformed Bible+commentary available.
Dr. Eckleburg is a seriosu scholar and I was wondering what his take was.
Apparently you find the study material to be highly effective in your reading.
I understand that Packer was the primary author of the longer notes.
