Traveling to El Chalten, Argentina.

I was fortunate enough to grow up living in Buenos Aires and Santa Fe, Argentina, and was able to visit some incredible places while living there. Unfortunately, I was young while I was there, and therefore did not know anything about climbing while I lived there. I am now hoping to make it down to El Chalten as much for the climbing as for the experience. From what I can tell getting there is difficult and the flights are expensive. Can anyone shed some light on the most affordable way of getting there from first hand experience? I have done pretty thorough research and just wanted to hear some advice/experiences from anyone who has recently/ever traveled down to that part of the country.
Saludos!

Flying to Calafate is expensive and bussing all the way there from Buenos Aires would be epically long! You could always take a flight to Bariloche, go climb at Frey for a few days then hop on a bus to Calafate.
