I have a Maclaren Quest and I reckon Maclaren's are the best strollers you can buy. So easy to steer and really lightweight. Unfortunately they are quite expensive, but I bought mine second hand from eBay for a bargain.

You will probably find once you have a stroller you will barely use your pram any more! They are so much easier to get in and out of the car and to manouver around shops.
