Travel System for Baby # 2?

RaeJean
I'm currently expecting a baby boy and I'm 30 weeks and 2 days along  ☺️ I have a little girl who is now 20 months old.  I've been looking for a travel system to accommodate both kiddos.  I was thinking of just buying an infant car seat for little man and then a double stroller for the two of them. Recommendations? I want something that's of good quality and don't want to pay an arm and a leg for it.
