CG Auctions blends eBay with Stock Media

CG Auctions: Sell and Buy everything related to Computer Graphics "...So basically if you have ever created any model, texture, blueprint, plug-in, script, shader, HDRI map, sound, tutorial etc. and you're it's rightful owner, or you don't use your old hardware, software, books and other stuff and you want to sell it, this site is perfect for your needs!...If you are a company which produces any of above mentioned goods you can sell them as well."

Might be an interesting option when considering the acquisition of stock art / 3D models etc. Also could be a nice channel for smaller content creators who don't want to pay fees, or can't stand waiting to get picked up by more traditional stock agency.
