Sort of depends on what you're storing, where you're putting it, and what time of year its is. We use:
- Wolf boxes imported from SA; plastic, excellent knock-about boxes for general use, stackable, strong, easily used - not air or watertight, not lockable
-
Spacecases imported from Oz; plastic, air\watertight, strong, easily stacked, configurable for equipment\tools\etc., lockable, colour-coded
-
Zarges imported from Germany; absolute favourite - aluminium, range of sizes, interiors, definitely the top of the line - but they stick to your hands in the cold
