Got my britax from mothercare. Priced 1200 onwards.

I guess you can check at babyfair if there are discounts. there is one coming soon.

Ppl have commented that halford is very nice as well and comfortable. I see many parents using halford and cosi. How old is your LO? maybe you can bring him around and let him sit and see which is comfortable.

I was lucky enough to inherit a baby car seat carrier (those basket type) from my sister. Sits until 6 months.. but on the way back from hospital cause lo head is so fragile and floppy neck, we held him only. Although dangerous, we held him for car trips for his first month. I think went out only 3 times all for doctors appointment.

We only got the Britax after that. Its comfortable and has a head support but still quite upright. At least 2 months plus when neck is stronger to use it. If you can.. see if you can get any infant carrier from relatives or friends first while you shop around fairs etc. scout pricing and safety.
