Seeing some $1304 out of MIA and a lot in the low $1500 range.
And for our Canadian/*A friends I'm seeing YYZ-EZE $1500, but it is hopping around central and South America on smaller Airbus planes on AV, TACA,and something called Trans American Airlines, which appears to be TACA-Peru. Didn't research it closely, but if stopovers are allowed it might be worth it to somebody.
