This time around I splurged and got the two carriers I really wanted in the first place. I got my Ergo on a deal a day website for 50% less than if I bought it retail. I found my Moby for about $30 shipped. I use both of them daily and my back and shoulders love me. Chasing after Archer with a baby in my arms just isn't a possibility so Fletcher is almost always in a carrier. They are also very useful for when he is cranky tired. I can get him to fall asleep in less than a minute once he is in a carrier. In fact he is asleep in the Ergo as I type.
Basically, if you are on the fence between getting the carrier you really want and a less expensive one, get the one you really want! I wish I would've had these with Archer.
