Need low-flow toilet: Kohler vs American Standard
American Standard Cadet 3 (elongated bowl, 1000 MAP, $298)
Kohler Wellworth (standard bowl, 1000 MAP, $218)
Would rather stick to a known brand like Kohler or AS, not buying a Costco toilet (that's what I'm replacing), and not looking to spend the moon on a Toto. Anyone have these or an opinion about them? Is the AS's "Rated Best Flush" worth the extra $80, or will the Kohler still make my #2's disappear?
