Query: Much better alternatives out there for baby carriers

Baby Bjorn was the pioneer for baby carriers 10 years ago but since then there has been an explosion in the market - slings, front carriers, pouches, etc. The BEST, in my honest opinion, is the Ergo. The baby sits with correct posture (The Bjorn is not so great for the baby's spine) and the parent is not in pain! I can walk for hours with my 20 lb baby in the Ergo -- not so in the Bjorn.
