I would get a used BOB Duallie before I got a lower quality brand new. Having a stroller that pushes nicely is really important when you have a 20 and 30 lbs kids in it.
Hopping on this thread as it's SORT of related - I'm expecting #2 in Feb when DS will be 22 mos. I plan on getting one double stroller, most likely BOB, and keeping my city mini single. I have another single jogger, but thinking of trading that in/selling and putting towards to BOB.Just curious if you really used your single strollers often when you had a double?
