Outside of Mexico I haven't found many really good beers in Latin America, as they generally lean toward light lagers & not-very-hoppy Pilseners.  But Mexico has some excellent beers, including Bohemia and Negra Modelo, two of my favorites. 
 
One of the best bang for the buck Belgian blonds is Affligem, which I get for $2.25 a bottle.  It's infinitely better than Leffe.
