a carrycot would probably still be the better bet as baby would be contained on all sides and kept warm. its called the dreami. Im not sure if it actually lays flat either, i think the moulded seat unit just lays back, meaning babys legs are still bent.
I have to say that the buzz, with its height adjustable handles can feel a bit wobbly when they are extended. But its a good pram / pusher with many good reviews.
I have the speedi and the zapp in my collection and i have no problems with Quinni at all.
Have you checked out the Dorel (quinni distributer) ebay page? often they have great deals on new or nearly new prams etc.
