Hi i havent got a phil and teds myself, but was looking at it when i bought my pram (i will have a new born and a 22 month old) we decided on icandi pear pram. I think its alot more versitile as you can your kids facing both ways, it converts into a single, has attachable car seat so you dont have to wake baby up when out in the car, has attachable carry cot instead of seat if your just going for a walk ect ect.... Anyway i wont go into any more details the links below to have a look.
Mine cost me ??650 but that was including the maxi cosi car seat and adapter that fits in the car. The actual pram is on sale for ??419.00,which includes 2 seats which are interchangable,carry cot, rain cover, footmuff and a few more bits i think anyway i hope you like it x
