A couple of other options in the Toto line:
CST484CEMFG -- Maris floor-mount. A dual-flush with the handle on the side. It also has the popular double-cyclone flush rather than the washdown flush usually used on dual-flush toilets. Appears to be on the way to being discontinued. (The wall-mount Maris is apparently still available, but the floor-mount seems to be hard to find on the toto web site anymore, which usually means that it's on the way out.)
CSt494CEMFG -- Connelly dual flush toilet. Brand-new dual-flush with the double-cyclone flush and the handle mounted on the side. May be hard to find for a few more weeks. https://www.totousa.com/ProductDetai...ProductID=1282
So many people like the Aquia I have to ask whether you might not just put the box of Kleenex to one side on the top...
