I'm a layperson with no Greek or Hebrew training, so in the past I haven't seriously considered adding BDAG/HALOT to my library. With the current 30% off sale, I'm now considering it.
I understand these two resources are considered to be among the best for word studies for those with training in the original languages. But I would appreciate hearing opinions on the value these resources might have to someone without the language training.
If you have language training, please try to imagine how useful these resources would be to you if you didn't have that training. If you don't have language training but own and use these resources, I'd be interested in how useful and helpful you've found them to be.
NOTE: As someone without original language training, I suppose an additional factor regarding the value of adding BDAG/HALOT to my library, would be to consider the lexicons I already own. I've included two screen shots below showing what I currently have.
