Ok so I am shopping for a convertible carseat. They range in price from $50 to $400. What the heck? They all have to meet the same safety standards so why would I pay for an expensive one?
So my question is... did you buy one that is more expensive and what did that get you that a cheaper $50-60 one didn't give?
Aside from there always being a huge range just from name brand/fabric/etc, the various car seats also work for different sizes/facings.
I have a MyRide 65 (Graco) from Wal-Mart and got it on sale for about $130. It is a fantastic seat and he can be rear facing for several years (he is 30lbs and still rear facing at 16 months), I believe it rear faces until 40lbs.
Our Eddie Bauer seat maxed out at 20lbs! There are also some ERF (extended rear facing) seats that will rear face up to 60lbs. Those ones will be more expensive but IMO well worth it, whereas standard seats will allow you to forward face at only 1 year and 20lbs (which is the bare minimum legal standard here in Canada and I believe in the US as well, with recommended rear facing at 2 years).
