need recommendations for a stroller/travel system..

stephany

this is pretty self explanatory. i'm a first time mom, and need some suggestions for a stroller or a complete travel system (like one that has a car seat that connects to it and can be used separately in the car) I have no idea what i'm looking for. definitely want something affordable but also reliable. I'm registered at Walmart, babies r us & amazon.com, so i want to add one to my registry. help please!!!!!
