I'm buying my toilet tomorrow. I have a couple of final questions.

Is there any data as to whether people are happier with the single flush Toto's vs the dual flush- or vice versa?

The Drake II is very close in price to the Eco Drake with Sanifloss at my local store. Given that would it be better to go with the Drake 2?

And does the Drake 2 work as well with low water pressure in an old home?
