The Toto toilet brand, which is what this is, is the best!  It's a bit more expensive, but worth it.  How often do you buy a toilet anyway.  It flushes with force more like an industrial grade toilet than a home grade so it is not prone to clog easily.  We purchased a house last year and have now replaced all of the toilets with ones like this.  Spent a little more money but have no regrets.
