I REALLY like the Graco Comfortsport. To me, the Britax are great, but not that much greater to pay more than twice as much as other car seats. The point is to secure the child tightly to the seat. I don't think a Britax, Graco, or Evenflo is going to make THAT much difference in a collision. They are all considered "safe" in the ratings and all constructed very similarly. Buying a new seat and installing it correctly according to the manufacturer are more important, I believe. I'd go with buying the 2 seats by Graco or Evenflo as opposed to the one Britax, because it takes a while to install the seat correctly. If you buy the 2, you can take the time to install them correctly and leave them installed, rather than rushed installs each day. Installing every day would get annoying to me real fast. Just some thoughts. Best wishes to you! :)
