I bought the Easy Rider a while back and I thought it was a waste of money. Maybe it just didn't work for me. I bought the Snoozer Lookout also recently and really love it so far. Here's a thread about opinions on the best car seat.

I think you are better off with something that sits on the seat, rather than just a harness. This way your little one can look out the window.
Oh, and the pictures above are awesome!
