Please excuse me for being too lazy to read back and find the thread, but elsewhere on this site is a discussion of a much easier way to unclog a Briggs Vacuity. I also think that if you go to Briggs' website, there are detailed instructions on the proper method to successfully (and easily) plunge one.
From what I've been told, the newer pressure-assisted (Flushmate) toilets are more quiet than the older models. I put in one made by American Standard back in '97 and, even though it sounded like an explosion whenever flushed, it NEVER clogged.
The professionals on this site swear by the Totos, so in my upcoming remodel, I'm going to give those a shot. I'm beginning to think the biggest problem is that people just can't adjust to the fact that a gallon and a half of water is not going to adequately flush down a half roll of paper and all the other stuff that goes with it. I know a half roll is an exaggeration, but if you tend to use a lot of paper, you need to "flush as you go."
