I generally reach for the one vol first, then TWOT for OT, then move to VanGemeren and Brown for the in depth stuff. I wish I had shelf space for the larger works. I am blessed to have quite a bit on CD ROM, so that helps.
have Gramcord/Logos on CD
usually "hit" BDB and BAGD for "quick studies" than TWOT for OT brown or Little Kittle for in depth studies in NT!
