In our water district, they are offering a rebate if you install one of the following toilets:
Caroma - Tasman 270
Caroma - Caravelle 270,305
Caroma - Reflections 305
Mansfield - EcoQuantum

In the MAP report, the Mansfield got the highest rating. But I am concerned about noise, since it is pressure assisted. Does anyone have recommendations for or against any of these toilets? Which one will keep the bowl cleanest? How loud is a pressure assist toilet? Which is best from a repair/maintenance perspective?
Thanks for your assistance!
