Convertible car seats are on sale at Amazon, and I'm trying to decide between the Maxi-cosi pria 70, and the Diono Radian. I've heard and read all the good reviews about the radian, and love that it has a steel frame like the Cybex Aton 2 LO is currently in. I'm concerned the radian may be too tall for my jeep Cherokee. I wanted to see if anyone had any feedback about the pria 70? LO will probably outgrow her infant car seat in length before she hits the weight limit, but no immediate plans to switch to a convertible. We just need two, and want to get one on sale now.
