Does anyone have experience with the Foremost Gemini 1 piece dual flush toilet? http://www.foremostcanada.com/products.php?prdid=243 Specifically, I am curious about ease of installation, flush mechanism quality, sound, and water spot. I like the looks of this better than the other dual flush toilets I've come across (e.g. TOTO Aquia). I know TOTO is the top of the line but maybe this one is passable? Thanks in advance.
