I reckon the ones you see on Exmoor are pritty good , money box with slot in front / side and a lockable door lower down . They then build a stone Cairn / stack about 3 foot cube and a little tunnel just long enough to reach in with a key and unlock , grab the dosh and lock again . So unless they have a breaker , then the money is safe . The only draw back is that it's a days work building but a sturdy set up !!
