I understand the appeal of facing out, but I have heard that the carriers that allow the baby to face outward are not good for their hip development because they are essentially hanging, supported only by their crotch, rather than being supported by the entire seat (see how the carrier comes around their hips on the Beco vs. the narrow seat support of the Bjorn). Additionally, facing out is not nearly as comfortable for mom/dad b/c the baby's weight is pulling away from your center of gravity rather than towards.
My husband insisted on getting a Bjorn b/c he thought our Moby (great carrier for a newborn!) was too girly looking. I tried it a few times and agree that it was not nearly as comfy as the Moby or the Ergo that we bought later. By about 15 lbs it was very uncomfortable. I still use our Ergo (similar to Beco) regularly with my 21 month old and it's super comfy.
You can use a Moby for forward facing either with their legs hanging out (hip issues?) or with them curled up. My son liked to face out with leg curled in the Moby.
There are some carriers that are similar style to the Beco/Ergo, but that allow you to snap in the support so that it gets narrower, so that you can have the baby face outward, but I can't remember what they are called.
If you can get two carriers, I'd highly recommend getting a Moby (or Sleepy Wrap) for the newborn stage and then a Ergo/Beco for past that.
ETA: I just read the other posts and the lillebaby everywhere is the carrier that I was thinking of above (that snaps). I think they get fairly good reviews, but not as good as Ergos and Becos.
