Supersunnyday and Neenewps - ok so manly slings - what you are probably looking for is a buckle-carrier so that it's just as easy to put on as a Babybjorn, looks plain and understated but has all the benefits of a proper seated position, support for the spine, more comfort for the wearer, the ability to back carry and that can be used for longer than conventional carriers.
Depending on what you want to spend, there are a few on offer although some are not 'officially' suitable for newborn - but 3 mths.
First up is yamo which comes in at around £75-£80 new but often shows up, used, on for sale boards on babywearing sites for around £40-£45. It is good and manly - it does state from 3 months but it has a really soft body and I don't see any reason why it wouldn't be suitable from birth to be honest.
Next is connecta which is around the same price as a basic babybjorn - about £60. And you can get this in plain black. The business is being sold at the moment, though, and they aren't too easy to get a hold of at the moment - but google away and you may find some shops with them in stock. You can also find these on the sale boards for around £40-£45.
There is also the more rucsack-like ergo which does state suitable from birth with infant-insert but without, it will be about 8 months until you get any use out of it. These are excellent carriers with a hefty price tag (£100 plus the cost of the insert insert which is between £10 and £15 I can't remember) but you MUST buy from a reputable supplier as ebay is SWAMPED with fakes at too good to be true prices.
Or there is manduca which costs from £70 upwards. I've never had this one I'm afraid, but it is apparently very adjustable and comfortable and good for newborns - again it looks manly but probably isn't quite as rucsacky as the ergo. These show up on for sale boards sometimes too but I can't remember how much they go for.
There are some more but I don't want to totally bombard you with info.
I can post some links to good suppliers if anyone wants me too.
Views on the hugabub - I have one actually. This is what is known as a 'stretchy wrap'. They do involve acres of fabric and a bit of a learning curve but they're not tooo tricky and when you get them working for you, they are about the most comfortable thing for a newborn. However, they only have a useful life of up to 4-6mths as the fabric simply isn't supportive enough when the baby gets bigger and you then need to get a different carrier or woven-type wrap rather than stretchy.
You don't need to buy hugabub brand - there are plenty of cheaper brands out there that are essentially the same thing e.g. sleepywrap or moby.
Again hugabubs can be found second hand on the for sale boards for around £20-£25
Hope some of that is helpful [bugrin]
