My SIL had this system with her 3rd kid and while she liked it, my niece grew out of the seat around 5 months old. She had the Chicco 22 though, not the 30. She was also a large baby, but you can't really control or predict that.
I have a Britax Chaperone carseat and a Peg Perego Pliko Switch stroller for my 3rd and like it a lot better than any of the travel systems I had with my older 2. Like someone else said, 1 stroller will NOT do it all, so don't get one with that in mind. Also, we rarely kept our kids in the carseats out of the car, so the amount of time we actually needed to snap the carseat into a stroller was minimal, so a snap 'n go frame would have been much easier for that purpose than a big, heavy stroller.
The Pliko Switch is nice because it reclines flat and can face you or out, so as a newborn/young infant, you can have the baby facing you, but not cramped into the carseat position if you're out for a long walk. Additionally, when the carseats are snapped into those travel systems, you can't readily use the basket, so that is something to keep in mind too.
Oh, and at 15 months, 31" and 18.5lbs, my daughter still fits in her Britax Chaperone with plenty of room to grow, so we have definitely gotten our money's worth out of this seat! It also has side impact head protection and an anti-rebound bar on the base, both features I like having compared to our old Graco SnugRides.
