Thought you'd never ask. First of all, by all means do not get any kind of a pressure assisted flusher. These create an explosion every time they are flushed. The toilets you need to look at are any in the Toto line. They are as quite as any and most Toto owners don't even own a plunger. Toto is the largest manufacturer of toilets in the world. There are a number of models, some quite economically priced, and then moving up in price. Best thing is, they all perform as a toilet should. Some have improved bowl washing. I'm sure there are Toto dealing in Houston.
