I hope you know the NABRE now comes in a Bible study format.
Look at a paper copy before buying it. The electronic version I have seems to have just footnotes and not much commentary.
Now the Orthodox Study Bible is good. Their footnotes point out the differences of the LXX.
=============================================================
A print version of this NABRE is good:
"New Catholic Answer Bible: New American Bible Revised Edition (NABRE)"
and I'd also recommend this New Testament Study Bible:
"Ignatius Catholic Study Bible: New Testament"
(I like the Orthodox Study Bible too. Their "Early Church Fathers" references add depth, and the many prayer icons they include in their Study Bible provide a glimpse into their deep contemplative prayer life too. They use the NKJV for their New Testament.)
