Personally, I wouldn't put my children in one. In fact I am making an effort to make sure no more of my baby dollars go to the Dorel company.
They make the cheapest product they can get away w/ and still meet the minimum safety standards.

There are some nice seats out there that don't run you $250, I would suggest looking at the Graco MyRide 65.
If you can afford it the Britax Marathon is a wonderful seat that should last her till she is ready for a seatbelt positioning booster.
We did w/o any extras for a month to purchase the best seats we could for our kids.
I know not everyone has ANY extra...so I understand...just don't skimp on safety if you can help it.
HTH!
