Which one would be better for a non insulated garage an evaporative cooler or an air conditioner?

for an uninsulated garage, i would say an evaporative cooler just for the money you will save on electricity. they do put some humidity in the air, so if you are in an area that is not very humid you should be ok. try to find reviews for your specific one 'cause some people love them and some say that you have to sit right in front of them to stay cool. i ume that the bigger the one you get, the less problem you will have
