we did spend about £500 on dd2's seat.
but that was because we wanted that seat (a Besafe isofix one) before it was available here, so we shipped it form Sweden.
but,a s i pointed out in my ost earlier - there are plenty of people buying the top of the range infant seat followed by the top of the range FF toddler seat.
which, if you look at the isofix models, comes to £400+. and the seat we have for dd2 is now available for less than that, and goes form birth to 18kg. so is actually cheaper than what a lot of people are already spending over the same period of time.
BUt completely agree with FrozenNorthPOle: what should be happening is that both RF anf FF seats are widely available, together with the relevant information on their safety and efficiency in the event of a crash. and then let the parents decide.
I hate the fact that for eg, Which? said that RF seats are "too complicated" for most parents to install - wtf? really? and that the seat manufacturers are dictating what we can choose form - Britax manufacture RF seats here in the UK, and then export them, only for retailers/parents to re-import them if wanted. and they say there is no market for these seats here... madness.
