We have the britax b agile for our first and we're happy with it. However it is a lower grade stroller and we needed a double. We ended up getting the britax b ready stroller and I'm like way too excited about it haha! It can convert into a double which is amazing. It just feels so much sturdier and you definitely get what you pay for with strollers. If you are a FTM and plan on having more than one kiddo I recommend getting one that can convert to a double. Worth the extra money! So many configurations!  We got it used for $250. It's almost like new. This stroller new runs for almost $700 with the second seat attachment. Keep an eye out for a used stroller!
