Ring sling - breaking in?

[StretchyCat]

Hello. I'm looking to buy my first ring sling, I've been using a borrowed one for a couple of weeks. I've heard its best to buy a second hand one to avoid needing to break it in. Is this a good idea? Where are the best places to look for second hand ones?

Thanks a lot
