The Consumer Reports ratings are very outdated, some of the seats on their list aren't made anymore, and many new seats have been put on the market since the last ratings were done.
I myself personally won't use a Cosco carseat either(and the brands Safety First, and Dorel are the same company as Cosco).
friskeymama, I'm not sure where you are in Louisiana, but you may want to try a Big Lots store, and seeing if they have the Fisher Price Safe Embrace. I've heard of stores in Texas and Tennessee getting some in(Fisher Price discontinued making carseats due to them not being profitable enough, but they were some of the best-made seats on the market)
You should make sure before you buy any carseat that it fits your car correctly, go to http://www.carseatdata.org
to see what seats were listed as fitting your vehicle the best.
And once you buy the seat, I'd recommend finding a certified child passenger safety technician near you, and getting your installation checked. PM me, and I can give you a list of techs in your area.
