I have 4 very recent (last 3 years) toilet purchases, from a Jaccuzzi- not worth discussing, to a Kohler (Ingenium, I think), AS and Toto. I think one must distinguish old from new, 5 gal flush from 1.6 from even less... The latter 3 are all excellent. Differences are notable from water spot size, to noise, to clean bowl. BUT I would still buy any of those 3 again, the AS cadet and Toto Promenade are the most similar in function, but the Toto is much more quiet, for certain. I find that MaP thing a little cumbersome to read... antss- yes, studies must show their data: study size, confounders, statistical significance of results, etc., ;-). Where is the p value?!?! And to note, in allll the yeeaars of using CR, which has been very helpful, one does need to understand that the rating is definitely cost related- best value for the dollar. I have purchased things that were top of the list, but definitely not the top product. I have learned. They don't always prioritize the same as I would, and it can be difficult to pick apart that subtlety.

Dave, The American Standard Cadet 3 has a boatload of different models. I found the One piece, Right Height (17 inch tall?) Cadet 3 to be a very good unit. The 1.6 gallon flush is quite powerful and does a great job. I haven't accumulated a bucket of golf balls to try in it yet, I keep losing them!! :)

It's always fun finding aftermarket kits when you try to fit a chevy engine into a Jaguar. I was lucky ones in the early 80's when I installed Chevy big block engine into a Jaguar and I believe the conversion kit was only available and would work only on cars no later than 95 or 96-year Jaguar. :-) That being said I doubt anyone makes it Universal bidet mounting kits for a seat to fit any toilet... If that's the route you want to take, go on Alibaba website and find a bidet seat there for a few hundred dollars Something Like This. and contact the manufacturer and see which model toilet that will fit. Just make sure you not gonna get electrocuted or something will melt on your behind because who knows what they add to their plastic composites :-) As you know cheap always ends up being expensive. Good luck

On the advice of my friend who has had both Toto and Kohler and replaced the Kohler toilets with Toto toilets, I am going with Toto I also wanted ADA height and one piece construction and a SKIRTED base so all those swirls in the trap didn't show and have to be dusted. The Guinevere is a pretty toilet for a traditional bathroom. I am having the Legato in the master bath because I wanted a Connect Plus washlet toilet there.
