Me and the missus have been looking for a pushchair pram travel system thingy for a while. We liked the look of this one but there seem to be a lot of dodgy reviews for it so be wary.
At £275 though it might be worth a punt anyway, especially if you live near a M&P store and can just dump it on them if it f***s up rather than having to go through their crappy customer services. Assuming you don't get a duff unit, it's a great price for what you get.
The other colours have decent reductions too but not as much as the blue/grey-brown colour.
