Spiros Zodhiates' original NASB Hebrew-Greek Key Study Bible on the left (dark cover) has served me well over the last thirty-plus years since I originally bought it some time during bible college. The publisher has since then, over the years, created the format in other translations and updated the title (it's now called the Hebrew-Greek Key Word Study Bible); and yesterday I finally put down the 55 bucks and ordered the ESV since that's the version most churches here have moved to. The margins are wider; the Hebrew and Greek Strong's Dictionaries and lexical aids from the first iteration have been merged into an annotated Strong's Dictionary with type that is much easier to read and the concordance has been updated for the newer translation. Otherwise it looks practically the same—important words are numbered using Strong's system, Greek verbs are shown with their parsings (tense, voice, mood).

With The Complete Biblical Library long out of print and now only available at significant cost as part of Logos Software's walled garden environment, this is a really good resource for biblical language junkies like me.
