Heya, still dopey, bare with me.
When I think of a sling, I think of this kind (more of a wrap than a sling)...

This is the kind I had.
This is the kind I don't like...

The one I like that I linked, these are the kind where you get a big long stretch of material, and you learn how to wrap it all around yourself, then drop baby in it.
If you are thinking of this kind, get it sooner rather than later, and get practicing so you are comfortable with it once baby arrives.
I cheated.
Mine was a wrap that was already kinda, sewn in place. All I had to do was pull it on over my head and go.
I absolutely loved it.
I could have baby right there cuddled up to me, it stopped "handsy" people pawing at him, it meant I still had both hands free to carry/do stuff/housework, if he was struggling to settle I could drop him in and carry on, no need to worry about hauling it up/down stairs in/out car or finding somewhere to store it.
They are brilliant for breast feeding as the material is really wide, so you can have the "V" where baby's head is practically open so people can see him, or pull the two sides right across so he's completely covered.
I used to put DS in, put my coat on over the top and do it up, people wouldn't even realise he was there. (Born in Jan so coats were needed).
I'll see if I can find the actual one I had cause it was soooo easy to use. Can't remember what it was called now without asking the ex to hunt it out.
I'll see if google will help. Xx
