I'd go with the last company on your list. Sierra Mountaineering is owned by Kurt Wedberg and he does an excellent job with Aconcagua trips. You will get so much more beyond your expectations and learn a lot along the way too. He does the Polish Traverse and the Polish Glacier routes.

I have done a trip with Rodrigo of Patagonias and was very happy. I am looking at them for AC ad well as Denali. Kurt, as an aside, I found your website hard to navigate. I never could tell if you guide Denali or not. Just my .02

I was very satisfied with my trip using Aventuras Patagonicas.

Woodie

We used Aconcagua Trek, also known as Los Puquios and were happy with the service. It is run by Rudy Parra & Heber Orona. We went unguided so we used them for mules and some other support services. With them we could a la carte as much as we wanted. I can’t comment on their guides verses other companies.

Daniel is a very personable guy and he is the one that owns the mules and provides services to companies like Jagged Globe. In 2003 he charges us about $1,800 USD for full service climb on the normal route. I'd check his prices.

Went with Grajales in Jan 2009. Really happy with the service so I recommend them

I made the Aconcagua summit in January 2012 with 3 friends. We hired an expedition to Acomara - AconcaguaExpeditions.com and I have to say it was perfect. Our ascent was by the normal route and our guides took us to the north summit1962 m. I am able to recommend Acomara AconcaguaExpeditions is a responsible company with excellent staff.
I hope you can complete the dream of climbing Mount Aconcagua. That's incredible. Regards.

I recommend AP. Excellent return on the investment (which is less than many other guide services).
