Selling stock footage
 

Is anyone here selling stock footage? A friend of mine is asking the question, he has a couple hundred short SD nature clips (Canon XL2) and wants to find a website where he could upload and sell that way, not tape/disk. I did a Google search for him, and iStockPhoto.com, pond5.com, MediaRecycler.com come up as possible sites.

Any other options, any info about their reliability greatly appreciated.
