We use our baby carriers far more than our buggy (we use our buggy less than 10% of the time). Just so much easier to do stuff with. The buggy is banished from town

Honestly, I could sit here and gush all day about how cool baby carriers are but you would probably get sick of it, and also that would be thread jacking

There are quite a few threads about baby carriers on here at the mo - a quick search would do it. Lots of people who are more "in the know" and fanatical about the best slings, wraps and carriers than me
Ok back to prams. We got our Mountain Buggy Urban Elite off TradeMe. It was only a year or two old but hardly used, looked like new and came with heaps of accessories - it was half the price of a new one. Don't know if we would have bought a brand new one. So that could be worth checking out if you really want a MB.
