Need Stroller/All-in-one reccomendations!

JB

My sister-in-law two states over has a bugaboo system for us, but with quarantine in place there’s no way we’ll be able to go get it by the time baby arrives in July!

Any of you ladies have good suggestions for a stroller with an all-in-one convertible car seat (infant rear facing to toddler booster seat/chair)? Ideally we’d like to spend under $400 if possible.
