Replaced all of the toilets in the house last year when Lowe's had some good ones on sale. They are really great and have substantially lowered my water bills because of the selective flush (low/high) feature. Only water out here falls from the sky and has to be transported from the volcano down to our little towns. It's precious, so I for one appreciate the intent of our EPA overlords even if it takes a decade or so to get the impact they hoped for. Sometimes, however, I will admit they do dumb stuff.
