I personally like Combi, it's very very light and easy to fold and carry around. However, it seems smaller than the European brand baby's stroller. If you don't have a car, it's better to carry the light one though, coz it is more convenient especially when you go out alone with your baby.
My own opinion: you should not expect to let your baby use the same stroller from born till 3 or 4 years old. Once they grow up and when they are able to walk, they will refuse to sit in a stroller. So, I think you should not invest too much money on it and don't really need to think of buying a bigger size of the stroller.
I just brought Chicco for 0 to 4 yr. $2300
very bad design, cannot fix into the car as its design for 0 to 6 mths ( baby sits with back towards car front),
my baby is only 3 mths old but have to sit like 6 mths with her face towards car front,
dunno buy this car seat
I am also thinking to buy the Chicco car seat which cost around $2300. It has 2 colours. I guess it is the one you had mention. Moreover, after your comment here, I don't think I will consider it.
I use Maxi Cosi , it seems to be most safe (according to a research done in Europe last year).
It costs me around $2000 for one use from 9 months to 4 years old.
