Plazmaman are Aussie made, ARC is Japanese, and both Saber and Hybrid are the same thing and come from China.
Both ARC and Plazmaman would be a good choice if you are looking for something top shelf and don't mind spending the money, however for the majority of street cars, a typical cheaper kit like the Cooling-Pro kits from Just Jap will be more than ample, have been proven 100's of times over, and have an Aussie warranty anyway if something does go pear shaped
