Britax Marathon, love it. The DD loves it too. Is the best carseat when switching cars too. Kind of bulky but not so much as to not getting it, fits fine in the van.
I thought to myself why did I ever waste my time with any other carseat with my boys who are now 15 and 8, and then I realized that this was my very first time ever purchasing a carseat the boys got them as gifts.
