I use a Facom 22" cantilever tool box but as soon as I got that it was full to the gunnels. Everything I managed to fit in has to be neatly stacked in. For organising sockets I got magnetic socket trays off of snapon and was kicking my self when I found that laser did the same ones £15 cheaper . A lot mid to high end tools already come with their own organisers and I try and use them where possible. I'm also going to get one of the veto pro PAC tool bags for my 1/4 inch, diagnostic, measuring and most commonly used tools, they are awesome have seen them used in the US, for any tools I need which are larger I'm going to get a Zarges aluminium chest, keeps everything portable.
