Well we had one picked out and we bought it, but now I didn't like it. We are returning it tomorrow and getting a different one. Here are the one's that we like. Let me know what you think.
1.Chicco

4.Britax
5.Graco

4 because we already have the carseat. Now I need the stroller.  

Britax is suppose to be good but we opted for the Quinny due to the wheels they are bike wheels that will be good for a lot of walking

Go for the Britax and get the B-Ready instead of the B-Agile. It acts as a double if you need it. Set up is a breeze and I can push mine with one hand. So easy. Plus it has 14 different configurations so you can get more use out of it. My 5 year old even sits in the main seat sometimes  

Chicco!! We LOVE ours. The carseat is also one of the safest on the market right now.
