PriusGuy04 - your Prius has a killer look !!
Ok, it looks like it comes down to Britax VS Cosco Alpha Omega. I bought one Alpha Omega from the internet and it came damaged

but that's for the van, the seat is quite large.
These are the only two well known brand for 5-65 lbs baby seat. I am leaning towards Britax because it seems to be more user friendly.
