I have two carriers in very GOOD condition.  I used the Ergo with my first child and the Bjorn with my second.  Both are comfortable for both you and the child and have excellent support when it comes to the back.

The Ergo carrier is green like the one on the site without the decorative flap.  And the Bjorn is the black and red version.
