I'm looking into car seats, and I'm not sure if I should get a "travel system" with the stroller and car seat that attaches, or a separate stroller and a convertible car seat.

I'm not sure how often I would use a stroller because I don't leave the house much, so I was thinking I'd want to save money with a convertible car seat and buy just the one rather than bigger ones as my baby grows. But my husband really likes the idea of the car seat that clicks into a stroller.

What do you guys have, and how do you like it?
