I looked at various brands... IMHO:
Bugaboo: Very nice design, very sturdy but can be a bit heavy if mummy is by herself
Combi: Very light, but personally it feels a little bit flimsy. Easy one hand fold/unfold
In the end I opted for a Chicco... sturdy, light-weight and easy one hand operation.
My decision factors are based on the fact that I may not always be with my wife when she brings it out. So a sturdy, light-weight easy to operate pram was a must...
