Hi:
We are expecting the baby in January so lets say small.
As far as the budget goes we really don't have one, we just really want to make sure our baby is safe.
We read a bunch of baby books that reviewed car seats and we/they like this one:
Graco 2007
SnugRide®
Infant Car Seat: $99
Link to car seat
I look forward to any help you can give us.
Thanks,
Mitch
