We hired one when our son was born for about $60 for 6 months from memory. It was very clean, the ambulance service fitted it for us and on return they even made sure that the car seat we bought ourselves was fitted correctly. Well worth evey cent to know that it is all safe. They are also great because when you get out of the car and bub is still asleep, the whole capsule comes out so bub doesn't need to be woken up at all.
