Do you dual flush?

At long last, a bathroom renovation is on the books. (Though in these 'dire' economic times, it is a little scary parting with such a large chunk of change.) But renovate we must! And we're trying to go as green as possible, so a dual flush toilet is on the list. What is dual flush, you ask? It's a toilet with two buttons: one that releases less water for yellow; the other that releases a bit more for brown. Surprisingly, it's hard to find a dual flush toilet. We went to one bathroom fixtures showroom and they had one on display, a Toto, which we decided almost immediately we did not like due to a weird channel where the seat folds up, which we imagined would harbor all sorts of bathroom nastiness. And then I'll read some review that says something like, "Dual flush toilets have come a long way...most work really well." Huh. I'd like a toilet that always works really well.

So, fellow EnviroMoms (or Dads, or People), do you have a dual flush toilet, and do you love it?
