What do you think guys? Are you liking the mesa or the aton 2 better? Baby is due in 1.5 weeks and originally I was going to get the Mesa but since production keeps getting pushed back I'm wondering if its worth it to wait. We have a coccoro installed until I decide and we could just stick with that but I thought with a three year old too it might be handy to have an infant seat this time. I really like the aton 2 bc it's super lightweight and though not officially endorsed I'm told it will attach to the vista with the maxi cosi adapter. Pros? Cons? Do you think I should just wait for the mesa? Is it really any better? Or just order the aton? Oh and is there really much difference between the aton and aton 2? Could I save a few bucks and be ok getting last years model??
