I am currently drooling over a baby citi mini double jogger. We rented one in Disney World last year and even my 6 yr old at the time fit in there nicely.
With my youngest and the baby only being right at 2 yrs apart I might splurge.
We have a joovy sit and stand. Honestly, I have never been to thrilled with it, it does great but it is heavy to push and turn especially once you wheel around one of the nicer strollers. Plus there is not a lot of comfort for a baby to go in there.
