You can find some good ones in the scrapyard. The Ford and Dodge fans work great and not to hard to swap in. Most fans I have used pull about 8-10 amps which is not much. In my Camaro I use a small one from an 80's GM with the 3rd gen aluminum Radiator and it stays between 185-195 on a 90 degree day. I also use a cheap parts store thermo fan controller w/relay. The only thing to make it better would be a way to shut it off after 15 mph where it starts to impede airflow.
