including the KISS and Air Breeze. http://www.naviclub.com/Test_comparatif_eoliennes_marine.pdf
It does a good job at comparing pros/cons of the models (parameters are efficiency, weight, noise at various RPMs, price, quality of construction, etc.) You'll find a comparison of the KISS and Air Breeze there. For me, it came down largely to price and ease of purchase. (All in all, it seems I could have spent just a bit more for a KISS and had something that is more easily field repairable, i.e., on board --the Air Breeze is not designed really to be opened up and fixed by the user. Ampair units are also designed to be easily repairable/serviced by the user.)
