Gerber is not a toilet that is recommended by most participants on the forum. The Toto line has by far the superior products and models that will fit every budget and style. I would encourage you to consider more than the MAPP ratings which when over 500 have very little relevance and are somewhat contrived anyway. I would also suggest that you consider that your are looking to purchase an appliance that should last for 30 or 40 years and that is used several times each day by every member of the household. What you want is a toilet that will never clog and that will need little maintenance during its life, and what it does need is inexpensive and can be done by the homeowner.
