I am 27 weeks pregnant with my PFB and now starting to buggy spot in earnest. I?d like to get a travel system that will hopefully do us from birth to walking without the need for further pushchair purchases. The Bugaboo Chameleon is just too expensive to consider, but I am rather taken with the UPPAbaby Vista, which seems pretty comparable. Does anyone have the Vista and have opinions / experiences (positive or negative) to share? It?s a huge purchase so I want to get it right.
