I installed an American Standard Champion 4 a few years ago in our bathroom that sees the most #2 action. The online reviews of this toilet I've read on terrylove.com are not good, but I love it . It's only clogged 2 or 3 times in 4 years, instead of every time like the circa 1995 Mansfield low flow it replaced. I have had to replace the gasket at the flapper valve, but other than that it's been fine.
