I've just discovered this website, and it's awesome! It's called ReCrib, and it's a place for buying and selling gently used, high end baby gear.
I'm thrilled to find this, because we strongly believe in buying quality, but we can't always afford high-end products.
I even found a Stokke Sleepi bed on this website for $375 (typically $800+).

I thought I would share it here - http://www.recrib.com

Enjoy!
