I went to four different plumbing supply stores here in Portland, (no big boxes). They all recommended the A.S. Cadet 3, and the Drake. There were some others that they showed me too, but those were the main two. Two of the places I went to had the Drake in stock but not the Cadet 3. They still recommended special ordering the Cadet 3 over the Drake. I know this forum tends to be a Toto love fest, but I went with the A.S.. I have an existing Toto Aquia II in my other bathroom right now that works well but I hate having to brush it every other time it's used. I purchased from a local plumbing supply house that does the majority of their business with just plumbers and contractors. The bowl, tank, and soft close Church seat came to $217. The install went great. I will let you know how it works out.
