I scored a 20-30lb box of taps at a flea market. Sorted (and de-greased) them over the course of a few months. I put them in small acro-bins.
I probably have (20) ea of 1/4, 5/16, 3/8, 1/2, 5/8. Not so many #10, #8. The bins were convenient, they stack nicely, and I can grab the bin with the size I need, then go to the bench and hunt for the right one (course, fine, starter, bottom, etc)
