Why settle on a normal tool box when you can have your own Snap On truck to keep all your tools in? Keep it parked in your garage for quick access and easy to take it all with you if you're working somewhere else!
Buddy of mine bought an old tool truck and gutted it for his band's equipment. I bought all the mag rails off him. Don't know why I need 40 mag rails but I have them all over the place now.
