Anybody been to Argentina...?

I've been thinking of of riding thru Argentina in the next year or two.

Has anybody done this before?

I'm trying to come up with a budget, incl. bike rental.

My rough estimate is about R25k for 10 days, including flights, fuel, visas, accommodation, rental. This figure is based on some riding pillion, to share the costs.

I'm keen to hear from you, or even if you know someone who has done it.
