You may also want to link directly to a site where you can buy good topo maps for Argentina. These are very useful for mountaineering in the outback. GeoArgentina

There is a mistake in the link of "proyecto Mapear"
The site is
http://www.proyectomapear.com.ar/
(To use with Mapsource -it is free - Information from all Argentina)
Another good site is
Viajeros http://viajeros.freeservers.com/ViajerosMapas/
(To use with Mapsource - Information only Northwest of Argentina and the South of Bolivia)

would be nice if you (&/or others) could also post some reviews of each (best, worst, why etc...) though that maybe a lot of work.
Great addition though.
