Anyway, a few years back we (i.e. wife + me) toured for one month South America for 2500 € for two (yes!), which included all food, hotels, entrance fees, e few car rentals and trains but not air fares (we were criss-crossing the southern part of the continent from Ushuaia all the way north to Lima); if air travel was included (w/o the TATLs), the total cost for two was much less than 4000€. When we came home I checked the cost of organized tours. The cheapest I found was 50% more expensive for two weeks! Unfortunately, you'll have to decide based on what they write in their offers, which is often rather far away from the real thing.
