Thanks for the review. I just purchased the Toto Drake II with the cyclone flush for a friend so hopefully that will be good for the money. I know exactly what you are talking about with the seats. My Kohler Power-Lite had a soft close seat that made you feel like you were going to fall in the bowl because the edge is higher than the inside rim. I didn't notice it being sharp, only that I could not stand to sit on it for a second longer.
I too got the Bemis soft close seat and have been extremely happy with them with the exception that they scratch easily. I will often use toilet paper to wipe dust off of the cover and you see swirl marks as if it were a black car!
I had considered the AS but was not happy after I saw the reviews so I'll try the Toto and see how that does.
