So, I admittedly go a little nuts researching things, especially car seats. We won't be buying much of anything for this babe, so I'm willing to pony up for a really good seat. Anyhow, I found one that I think looks amazing, the Cybex Aton Q.
The big pros for me are the safety features - it has a "load leg" that goes from the base to the floor board of the car, so it absorbs energy in a frontal crash (the Nuna Pipa also has a load leg). It also has telescoping arms that absorb energy in a side impact crash (American brands are apparently behind in side impact technology). And it's designed so infants lie almost totally flat so they aren't scrunched up and reducing lung capacity. Then as you raise the harness the angle a adjusts to give more incline.
I guess it must be popular; the online retailers are all sold out of it now. I'll probably buy it as soon as it's available again so I can let it off-gas over the next seven months. It's $350, which is not too insane I don't think.
