Pushchairs?

Hey mamas :) I've been looking into buying a pram for my first child, but I'm so stuck! I really want one that I will be able to use from birth until about 3 years. I walk everywhere and use public transport regularly, and baby will very rarely be in the car unless travelling to Dr's appointments or to the In-laws. Im considering the Bugaboo Buffalo or the Bugaboo Cameleon 3, as my friends have had them, and had nothing but good things to say about them. Have you had any good/bad experiences with that brand, and if so, what? Also, what pushchair will you be buying/have bought, and why? Suggestions are welcome. T.I.A x
