I use Hansen socket racks, el cheapo wrench racks from HF (about $6 I believe) and foam for all my ratchets, extensions, U-joints, etc..., and screwdirvers, thats it. Pliers you dont have to worry about rolling around.
You shouldn't pay more than about $10 a rack for the Hansen stuff. It helps to look on ebay sometimes. The wrench racks from HF are pretty nice all in all, they hold my wrenchs from 1/4" to 1-1/4" all on one rack. They have an annoying handle on them, but I just sawed mine off. The tool foam is a TOTAL PITA. Probably took me 3 hours or more to do my entire drawer. I'd still say its totally worth it. I can't stand stuff rolling around in my box every time I close a drawer.
