YANBU - I am due in April, have been looking around and am shocked. My DD is 9yo and I got a bargain with her Graco travel system - bought by a friend just 6 months earlier, too big for her car and only ever used to push her PFB from the car park to the shops.
She sold it to me for £100 and I used it for 3 or 4 years - it was worth it's weight in gold.
I walked everywhere, so a big/sturdy pram was what suited my needs.
If you are more of a car-centric family, do not go for big and sturdy.
If you do a lot of walking (ie leisure time, out and about in the country) then you need lightweight but durable.
If you use the bus, you need to make sure it doesn't take up the entire pushchair/wheelchair section and can be easily collapsed should the need arise.
Bearing all this in mind, I trotted off to Mothercare (having got a feel for what is what in the world of prams 2012 online). I was shocked, you definitely pay the higher end for the branded prams.
Not worth it. From what I can work out, Graco is not-cool anymore (whereas it was in 2003
) but Quinny and Stoke are tres-chic.
You get a decent, all inclusive, Graco travel system for around £400. Similar spec on a Quinny would set you back double that - for the privilege of wakling around with a brand stamped across the pram.
I'm looking at a Silver Cross at the moment, based purely on what is on offer, sturdiness and having spoken to a few others/read a few reviews, it seems to fit my needs.
I plan to wait until January sales and see what I can get for my money. I do not want to spend more than £450 on everything.
The baby-industry plays on new parents innocence/naivety and they would sell ice to the polar bears with a 150% markup if they could 
Thanks for letting me vent my pram rant, it has been brewing for a while now!
