Double strollers

This is a question for those ladies who already have a couple of kids or are expecting their second child. I have an almost 2 yr old and I am looking to get a double stroller since I know it will be a couple of years atleast where both kids will want to be pushed around. Does anyone have any advice or a brand they particularly love? I know I need one that can support a car seat for the youngest baby and my son is pretty tall for his age (3 ft at 2 yrs old) so roomy is preferable. Budget wise I'm looking at $300 and under. Any suggestions or tips are appreciated!! Thanks :)
