We've just bought one as well - we actually ended up buying a travel system (Fisher Price) second hand. I was originally sooooo against buying any sort of safety gear second hand, but I've since found out that in WA we can go to either Red Cross (ambos) or Kidsafe WA and they do testing of any equipment so that we can make sure it's safe. Considering that the ambos hire out second hand equipment, I figure that there testing should be fine.

We ended up buying the whole system (capsule goes straight into pram) coz it seems so much more convenient, especially when I know we'll have a fair bit of travelling to do in the first few months.
