I have and use this Bible. I think it is the best study Bible out there (followed by the Ryrie study Bible), but it is now out of print and getting hard to find.

I do think a well selected study Bible can be useful so long as the reader kees in mind that the Bible text is God's Word while the studt notes are man's opinion.

One thing that I like about this Bible is that it only comes in the Authorized Version.
