Stroller Help! Please!!

There is so much out there it’s overwhelming. I’ve been to stores but am looking for advice on a stroller that’s not $1000. I’ve been looking at Graco and Chicco brands but there’s so many others out there and at some point they’re almost the same price as like the Mockingbird. Here’s what I’m looking for:

-Preferably would want a travel system or a stroller that has an infant car seat adapter.

-That down the road has the capability for 2 kids.

-That folds down easily.

-I live in a big city if that matters.

Thank you!
