If you're looking at the list prices, don't! Nearly anywhere you can buy the Toto toilets will sell one to you for (sometimes much) less than list price. For an approximation, check Terry's store price. He won't ship, but it's an indication of what is a fair price for the thing. Pretty much any Toto beats any of the older toilets out there...I have no experience with the Clayton, but do with Toto in general, and it has all been positive. At one time, Toto did offer a builder's grade toilet, it was better than most, but I don't think they do anymore in this market.
