I would be very wary of anything Argentinian. Their was tumultuous economic dislocation there only several years ago. That in itself doesn't render it unattractive for investment but the actions of the government were very dubious. They froze current accounts and seized assets which caused foreign investors in property and other more liquid assets to lose out criminally. Can a country with the potential for this to happen be counted as stable enough for significant investment. Notice that it is called BRIC not BRICA!!
I think you are about a few years too late, since they defaulted on their debt and their currency was cut in half. Check it out though, everything is on google, it's the internet yellow pages. I found this in 30 seconds. http://www.internationalliving.com/lp/argentinarelp?gclid=CJne5pXUs4oCFRNGGAodUA4suQ
