Take their Champion line — you have likely heard the name. Did you know, it’s got 17 different models in it alone (check the link back there)? Elongated or round, RH/LH (that’s right-handed handle and/or left, and it can make a big difference). And of course that’s not to mention variations in dimension — total height, tank height, tank width, etc. All these options come in handy when you have a “location” you MUST fit. (I know a Champion has saved *me* more than once.)
