I agree with the tails being annoying - I mind them less than DH, who if he's wearing the Close underneath his coat, does tend to look like an undertaker with coat tails! He tends to tie the tails around his waist at the front - it does look a bit naff, but is a slightly less feminine look.
It does take a while to get the hang of using, even though you put it on like a t-shirt. On the other hand, I'm not sure DH would have been prepared to try a stretchy wrap either, so from our point of view it was better. Both DH and my dad managed to use it successfully.
DS is now 5 months and I'm planning to get another sling (a Connecta - a woven semi-structured carrier) since I find that now he's big & heavy, he tends to slip down towards your kneecaps if you're not careful if he's in it for any length of time! It is supposed to be okay for babies up to about 30lb but I think you're better off with a woven sling for bigger babies. DS is 20lb and on the 98th centile for weight, so he is unusually heavy for his age!
Having said that, I would definitely use it again for any further DCs. I tried the Connecta when DS was 9 weeks old, but it didn't work so well for small babies as the Close did.
Having a sling has been the best thing ever for us. We had 5 weeks when DS wouldn't sleep in the day unless in the sling. And even now, he gets frustrated in the pram with the hood is up and he can't see anything, but is more than happy to be in the sling.
You could look on Ebay for second hand ones if you wanted one which was a bit cheaper.
