ergo was so uncomfortable and bulky for a newborn...she hated it....and without the infant insert she almost slid out the bottom once...oops. but i can see how dads like them. i preferred a stretchy wrap like the moby until she hit 12 pounds or so. after that i had a maya tie mei tei which i liked because it had the wide supportive straps of a wrap. plus, i wanted to be able to carry it around in a bag for when i needed it and you can't really do that with the ergo.
i like the suggestion of the babyhawk oh snap or the beco. maybe that could be the happy medium between an ergo and a regular mei tei. i don't know anything about them but the boba carriers are on sale on zulily today for $50.
for what it's worth although my dh said he loved the idea of babywearing (and "just wanted to tie her on like they do in africa") the only thing he really got behind (but still never got around to buying) was a backpack carrier.
