I just purchased two TOTO's from Terry Love with the TOTO "soft close seat". They work very well and are just cool enough to encourage me to close the lid after use, a trick my wife has been trying to teach me for 30 years. The only down side to them is they seem to have a bit of lateral play in them that does not exist in regular seats. The first impression is that maybe the mounting bolts are loose, but that is just the way they work I guess. It will be interesting to see how long they retain the soft close feature.
At $50 each they are a bit pricy, but since I was spending premium money for the toilets, I figured "what the heck".
