I just went the same rout as crOsh and bought a bunch of Stack-On units
2 each 60 small and 18 large units. I also have a smaller unit from before. In addition to getting a bunch of dividers I also got lots of extra drawers. I have found the large drawers work very well in old CD racks for over sized parts.
I have a mish mash of parts from years of tinkering and I also have new parts I am getting for various projects. I have a rack designated for resistors in a 2 stage sorting order, 6 drawers cover the multiplier bands and then they get sorted up from there into finer needs. I keep printed cards in each drawer and colors and values taped to the front to help in quick mindless sorting.
So far so good, but I am only about 10% threw sorting my crap. I do love the new system.
