I've been using a Craftsman 12 pocket tool pouch, but it's discontinued:
It's got a good layout and a kickstand which is great. It's too big to wear, but the strap and hardware are all good quality.
I also recently got a Veto TP3 pouch that can be worn on a belt for when I'm on a ladder. It's big enough to carry a handy number of tools and it can be worn in the front to avoid whacking stuff as you walk through a house, but it's a little bulky to wear constantly IMHO:
It's a shame Veto doesn't make something like the Craftsman bag - I've gotten really attached to the layout but the Veto quality is much higher.
In my truck I have
Ranger shelving and cabinets. That stuff rocks - especially the sliders that pull out to the side where I keep all my power tools. I never have to crawl in the back looking for a tool.
I have a small collection of stackable Stanley bins that I use, but after seeing the ones Randy uses, I might have to re-evaluate that setup
The only downside I see to them is that they have opaque lids which makes it impossible to see what you have without opening the case.
I also recently got one of these (10-gallon Brute can):
It's great for throwing the tool bag, nail apron, a few power tools, materials, etc. into and loading onto my hand truck for working in town. It's also good for trash
