Which stroller is best...

Mary • Mom of 4 :) Not needing any more!
I am pregnant with baby #4 and have decided to skip the "baby bucket" and go straight to a Britax convertible car seat with this one. My previous 3 babies were all over 8 lbs so the infant carrier just doesn't last us very long. 
So, since I am going to be using a stroller a lot, I need a good one, but I don't want to spend a fortune. Suggestions? Thanks!
