http://www.iihs.org/news/rss/pr100108.htmlI wanted to pass this along. The linked article is above, I just copied the main evaluation. I also wanted to point out the article says the Graco one is $50, but you can get the FP Save Voyage through Albee Baby for $30. It's basically a no-frills version of Britax carseats (actually manufactured by Britax).
