The All-In-One systems consist of a cover that is permanently attached to the absorbent part, just like a normal disposable diaper. That might make them a little easier to assemble, but they take longer to dry (we are going to hang dry ours) and the whole diaper, including the cover, has to go in the laundry. AIO is not for me. It does not seem as green to me either, but that is just my opinion.
The Flip diaper cost 13.95 if bought from a store. Though, if you go to ebay.com you can find them for much cheaper. There are many people who give up on cloth diapers no matter what system they use, so they sell them after only one or two uses.
Another way to cut down on cost and to keep it green is to plan on using it for multiple children. Since Greg and I plan to have one more at some point, we can use the diapers for the next child too. With that in mind, I do not plan to buy any that are pink or girly this time around in case the next one is a boy.
We will also keep track of our spending on diapers and have an update after the baby comes. =)
