I would NOT get the two handled one (Britax one). I had one very similar to this through Kidsafe for my first two babies and it was not comfy to carry.

With DD we bought a One Safe brand one 2nd hand and it was great! One handle design is better than two, I think. She was in it (and took it out of the car, carried it into friend's houses, kindy etc) until she hit the 9kg weight limit (at about 5 months!). It didn't clip into our stroller but it was still good. We used it like a rocker/seat thing too while we were at home.

Some people complain that they are too heavy etc, but I found it was ok (though I am pretty muscly).

Anyway, the Babylove thing looks good IMO.

Hope this ramble helps!
