Argentina is great for international tourism I can assure you, cheap and classy, if you handle Euros or Dollars of course, if you ever come visit the country I highly recommend Bariloche, relly, it's beautiful, "El Bolsón" is nice also, a lot of green and nature, also full of international tourism.
If you want tango and city-life Buenos Aires is nice, but as all big cities it has bad parts and good parts :)
