I think you can get all these features in a Dartmouth and Drake too.
I just put a Promenade (new model 424, not 724) in this weekend sans sanigloss(wanted it but not readily available). It looks great and maches my older home. I got the seat recommended on the Toto website sizzle sheet. The dealer book was recommending the traditional seat (154?) which is more expensive.
Initial reaction is that I don't think it as powerful as my Dartmouth. I'll need to check again but the flush valve might not be the same as the Dartmouth.
It is right against the wall with a 11 3/4 rough in, I thought I would have 1/2 inch left.
