TBH personally I think it's a waste of money buying a really expensive pram. Just go for a decent CHEAPER pram. It doesn't have to be an iCandy or anything half as fancy. I went through 3 kids without even sniffing at an iCandy pram lol.
edited to add :
there's a graco on Argos on offer for £109.00 (Graco Mirage Pushchair Travel System)
I had a Graco myself but a three wheeled one, and it was excellent but my only grumble was that the wheels didn't swivel.
I also had a graco tandem stadium duo which DID have swivel wheels, and that one was excellent.
I'd buy that one from Argos if it were me, and a car seat (to make use of the travel system). There's no need for prams that cost the earth.
In fact, a lot of people these days don't even use prams, they use slings. Slings give me backache though, but each to their own.
