New car seat

We recently bought another car seat, Sunshine Kids Radian65SL from Albeebaby.com since Cole is starting to outgrow his infant carrier. We really like our Britax roundabout but the one bad thing about them is that they are really wide. You can't fit 2 of them side by side. The Sunshine Kids car seats are highly rated and have a slim profile. They are also really heavy since they have a steel frame. In this picture you can see the Radian65(left) next to the Roundabout(right). Notice how high the Roundabout sits as well as how bulky it looks.
