I'm with Rumples on this one. The worst exchange rates that I have ever experienced were (1) in airports or (2) when getting some cash in the currency of the country I am to visit from my bank or credit union prior to the trip. Follow Rumples advise and use your CC upon arrival. If you don't want to leave a paper trail than shop the cambios in the downtown section of the country you visit and shop for the best rates and lowest fees.
My advise is only buy enough cash beforehand in order to get where you are going. I seem to go to the same three places to hobby so unlike my friends and colleagues, I am not in a rush to dump CDN, Reals, or Euro on the last day of the trip. I hold on to them for the next trip. They go in my safe with my passport. There is always another trip.
