What do you keep your tools in?

I've recently ditched my classic steel cantilevered box (http://tinyurl.com/mdxlea6) to an open tote bag. (http://tinyurl.com/n6hwljx)

Can't fit everything in, but when I finally clear out the garage, my dream is that I'll have all my tools mounted on the wall and I'll select what I need when I start a job.

Do Londoners even have toolboxes?
