Hi all, I am a lurker coming out because unfortunately we were in an accident yesterday and my kids carseats got to do their job and they did it with flying colors. We had 2 MA's that now need to be replaced. So I am just not sure what to get now. Insurance is allowing them to be replaced. I just need to turn in the seats, but can keep the covers (yay!). DS1 is 4.5, 34lbs w/ a 14" torso, and DS2 is 2.25, 28lbs w/ a 13.5" torso. Both boys were on the 3 slots up. I don't know if I should get 2 more MA's since they both loved them and their covers. DS1 is no where near ready to be out of a harness (nor do I want him to be after that), but I was thinking maybe Frontier or Nautilus for him. Is there anything else out there? What about all the problems with the Frontier?
