(1) My inch "go to" set. Drill & tap index bought (populated with Cleveland D&Ts) from McDonald Industrial in Albany, OR some years ago - old and dusty on the store shelf, and a real bargain at somwhere in the $100-200 range. The little can on the red base is my "tap dip." It's a vintage 35mm film cassette.
(2) My "equivalent" metric set, I bought the base not too long ago, and had forgotten how many mistakes it had in it (first saw one back in the '70s). But useful nonetheless. I add PVC half-pipes on the sides to store the dies.
(3) A storage drawer set I got (at a garage sale?) a few years ago, for my inch spares, dies, and larger sizes.
(4) Tap and die wrenches, more taps, etc. in plastic bins nearby.
PS - I have a number of odd-pitch metric taps & dies. If anybody needs such an animal, PM me and I'll look to see if I have what you need.
