Ok so I intend to be in South America literally until the money runs out. Assuming I don't eat much, I use the cheapest accommodation I can find, will be travelling by bus unless I acan find a cheaper alternative but have a penchant for tours, sight seeing, tourist attractions and doing as much fun stuff as possible, roughly how much would I need a month? Either in NZ$ or British Pounds.

Yep, I know this is a very ambiguous question and will vary massively from country to country but a ballpark figure would be really appreciated
