Graco travel systems?

Hi everyone!
I've been doing some research on car seats and travel systems and think Graco snug ride click connects will work best for us. The travel systems seems to be the best deal. I have to go out of town to Babies r Us so I can try them out, but in the mean time, does anyone have any advice/experience about these? I'm looking at the 30 or 35 (regular or LX) but am overwhelmed with all the choices. Any input would be greatly appreciated! We are fortunate that my grandma is buying it for us, but she's a planner and won't rest until I pick one out! 😊
