Since my 330 is always breaking and I'm helping my buddies, I bring a lot of tools. The problem is I need to rummage around to find a socket, wrench, or anything in a regular plastic tool box.
This
Track Tool Box is brilliant. Just big enough to fit a torque wrench and breaker bar. It has a compartment for hardware and stuff in the top. It is not too heavy but seems sturdy. Then the most important thing, the drawers are sturdy and slide nice and smoothly. The drawers lock when you close the lid. Price? $40 from Home Depot. So I need to change brake pads? I go to my toolbox, I quickly grab a 5mm socket, extension, and ratchet. Instead of getting stabbed with my utility knife and emptying out half of the box to find the right socket.
Just thought I'd share.
