We bought the Graco frame stroller to go with a car seat we inherited. It's light, easy to fold/unfold, etc but only holds the car seat so you have to buy another stroller when the child outgrows the basket carseat.
I lover my maxi cosi travel system, its super light.
I got the mosaic graco travel system... i love it, its not bulky when you fold it up, it almost reminds me of an umbrella stroller but bigger, and its handles are 2 separate bars so when i go shopping i hook all my bags on them, and thats where i put the diaper bag... and i live on a farm and have no trouble on the gravel... my only pet peave is the canapy doesnt protect from the sun that well at times- i would drape a blanket over to help... oh and it doesnt have a tray that some do for snacks and what not... but i love everything else about it...
B4 I buy anything I always look at the reviews it helps a lot. U Might find it helpful (graco spree travel) this one very good review plus I bought it it's really light weight I'm happy with it:)
I got the orbit system its pricy but seems nice
I have an Aprica stroller for my son and I love it. It takes some getting used to, to open and close it but it's like a nicer version of an umbrella stroller. it won't hold a carrier but that's fine with me. It says from about 15 lbs up to 70 but for me that's not a problem as I usually use a carrier or wrap when my babies are little. The seat reclines and the sun shade is very large. I just wish it had a bigge basket but considering it fits in the back of my Prius and takes up no more room than a regular umbrella stroller I can't complain too much. My old Graco travel stroller took up the entire back and I had to wiggle groceries in around it.
