FWIW, in DH's car (at the time), the Scenera was a much easier install than the Roundabout was! It all depends on the car and where you're putting it.

DH never wanted the Roundabout in his car b/c it was such a pain to get in there.
They were saying that a 10 month old shouldn't be in a *Regent*. And they shouldn't be.
OP, are you looking for a new seat b/c you need one anyway? Or because you have something that's not approved? If it's the latter, are you sure it's not approved?[/QUOTE]
I wrote this back in January prior to our trip. We currently have a carseat that is good up until 32 lbs, but we didn't want to bring that whole seat plus base with us on the flight. Anyway.. Everything worked out.
