I use the one in your original post for my findings. 95% of mine are sterling, so I keep the copper and gold only in a couple of drawers (my larger chain I keep in awesome little boxes from Ikea
http://www.ikea.com/ca/en/catalog/products/80098583/). I use the largers drawers for other things like gemstone and shell pendants, watch faces etc... The smaller ones are organized by type (i.e. toggles, other clasps, earwires, rounds, rondelles etc...).
I also have 4 of the larger 60-drawer ones (

I love them! They've worked really well for me and they transport fairly easily. The great things about the drawers is you can easily switch them up between cabinets if needed. A few of my shows I've compacted my necessities into one cabinet and brought it with me so I can work while I'm there and offer custom on-the-spot pieces.
