Bigmak 380
Price: £84.95 Capacity: 320 litres
Clearly a budget offering, but the Bigmak is a usable box all the same, and its thick plastic is sturdy. A large external clamp holds together the only place where flexing could be an issue. Central locking is included, and the mechanism is outside the base, maximising capacity. But the 380 is a self-assembly unit.
