Overlooked gems in Logos

I wanted to share two resources that many no doubt overlook.  First, when I attended Camp Logos a few weeks ago, I heard Morris Proctor say that the UBS Bible Handbook series had become his favorite commentary in many ways. After upgrading recently and acquiring them, I have to agree with him. I probably would not have opened them due to them being "translator's handbooks" and figuring that they would be so technical it would not be worth the time to plow through them. Don't make that assumption!  They are wonderful, unique commentary set that is well worth consulting all the time.

A second hidden gem is Bob Utley's Study Guide Commentary series. I overlooked these because I thought they were written striclty for Sunday school teachers and would offer nothing that I wouldn't come across through my other resources. In recent weeks, I have been pleasantly surprised to find them a valuable resource alongside my critical commentaries, expositional commentaries, and original language resources. Yes, they are concise but they are not shallow and occasionally have some very valuable insights. Well worth the five minutes or so it takes to consult them for a particular passage.

What are some other hidden/overlooked gems you have found in Logos?
