Stroller/Car Seat Recommendations?

Kelsey
I am so overwhelmed by all the stroller and car seat choices out there these days! Do you guys have any recommendations? Here's what I'm looking for (in order of importance):
Car seat (or infant seat? Is there a difference?) transfers directly from the car to the stroller (car seat included is preferred)
Stroller can be used for infants to toddlers (it "grows" with your child)
Not *too* expensive
Stroller is lightweight and easy to open/close
Collapsed stroller doesn't take up too much space in the car
Stroller has extra storage for diaper bag/toys, maybe a cup holder or something for Mommy, etc. 
Thanks! :)
