I would 100% suggest the CHICCO travel system! The car seat itself is awesome, it has a very easy to read liquid, level indicator on the base, so you know that you have it positioned correctly in your car! And the car seat carrier has a one hand release that makes it easy to get it in and out of the car and stroller. I think it is the lightest wieght I have pushed around. I am having twins, so I am having to go with a twin travel system, but if I was only having 1 I would go with CHICCO again!
Also, Babies R US is the BEST place to register! They are so nice and easy when you need to return something. We also registered at Target and it was a hassle EVERYTIME we went to return something. We got a bunch of duplicate gifts from target becasue they did not update our registry very well. We had no problems and nothing but help at Babies R Us!!
