Unexpected Necessity: Circular Shelving

On a quick shopping trip the other day, I was happy to find this creative, circular shelf in a bedroom display at Anthropologie. Circular shelves are a great way to mix up the monotony of a room, plus I love how this one doubles as a headboard!

I snapped a picture, then went home to do some research for other circular shelving sources. Sadly, most of the ones that I found were rather expensive. Does anyone have any resources for less expensive circular shelves? Do tell! In the meantime, check out some of the beautiful designs I found.
