We just got the Safety 1st Grow and Go for our toddler and have been happy with it so far. It was affordable and easy to install.

Swivel car seat recommendation request
I'm looking for a swivel car seat under $250. Any recommendations? I've seen Safety 1st has one but not sure how it compares to Evenflo.
