I don't know how many homes I might end up living in, but I will ALWAYS change out the toilet seat for a Washlet.  This is now my second as I have left my first in a vacation home that we own.  This model, I believe, has been discontinued but there is another to have taken its place.  It is the entry level in the Toto lineup of Washlets and well worth the price.  Quite a few functions, too.    

Pros: Does what it says!  
Cons: None.
