You can do a lot with $160.

The rules of entering different countries always vary, but if you’re entering Argentina, be aware of a reciprocity fee which is atypical compared to other countries.
Since 2008, U.S. citizens were obligated to pay USD $160 – a reciprocity fee – when entering Argentina. Valid for 10 years, this was Argentina’s answer to America since we also charged Argentinians the same fee as part of our visa program.
Argentina, however, finally suspended the reciprocity fee for US citizens during March 2016. According to Embassy of Argentina in the US website:
In order to strengthen the relationship between Argentina and the United States of America, the Argentine Government has resolved to suspend the collection of the reciprocity fee from US passport holders who visit our country for less than 90 days, for tourist or business purposes.
Unfortunately, reciprocity fee still applies to Australian and Canadian passport holders.
