Re: Britax infant seats???
The Britax infant seats are nice, but there are lots of nice infant seats on the market today. Basically the Britax options are the B-safe or the Chaperone. Other good choices are the Chicco Keyfit and Graco seats (though I haven't kept up with the Graco offerings). There may still be some 22 pound Graco back-adjust seats, if so avoid those. Some people really like the Safety 1st Onboard 35. I think Evenflo has stepped up their infant seat game lately, though I can't think of their nicer models.
The First Years Via is a nice option, and so is the Cybex Aton, though they might be hard to find in stores to see in person.
Sorry I'm not more help!
