I have added some of my favorite links to my "sites worth visiting."
You can purchase Patapum(s) and Patapum Carrier(s) from here.
The Mei Tai is pretty popular as well, and can be used as a back pack carrier. The
Ellaroo Mei Tai is probably on of the better known makers of Mei Tais. The Podaegi is a lot like a Mei Tai except it has two straps vs. four.
Also, if you are looking for a community then here is a good place to start. If you do not yet have a Baby Sling, Mei Hip or a Baby Wrap then here are some links to find them.
If you check back in the furture the Babywearing blog should have some product reviews of the Ellaroo Wrap and the Moby Wrap
Here is one more babywearing link worth checking out
