NUNA Pipa/Mixx or Tavo travel system

Paige
We've been looking at infant carriers and strollers and I am IN LOVE with the NUNA Mixx travel system - it's expensive, but the stroller has all terrain tires which would be great where we live. However, I only know a handful of people who have NUNA brand things! Does anyone have the Mixx or Tavo travel system who can give me an honest review?
