As I read your input, I started realizing that the underlying question is what do I want in a tool kit, and how organized I want it? I have boxes of various tools. I guess if I'm willing to challenge my OCD and risk not having everything neatly organized in a plastic box, it's just a matter of selecting the right list of tools and calling it a tool kit. Then it's just a matter of finding the right tool bag.

So what's your favorite tool bag?
