You guys are going to call me crazy for suggesting this but here is how I would get money in and out.
I'd buy Bitcoin locally in pesos or dollars and transfer to Coinbase.com in US then sell for dollars. Coinbase links to your bank account to transfer funds. 15 cents for transfers 1% commission to trade. You could do same with Bitstamp in UK.
If you want money here at blue value and to avoid the AFIP, just do the same in reverse. Buy BTC and sell or trade locally for pesos at the Bitcoin Argentina Google Group or LocalBitcoins.com.
There is a substantial market here for BTC and transferring money is one of the best use cases for it.
