Where to buy and sell vector illustrations

You probably know that there are sites in which you can buy and sell stock photos, but did you know there are also sites in which you can buy and sell vector illustrations? There aren't as many as the stock photo sites, but there are still a lot of great illustrations available.

60 free stock photos from iStockphoto

For those of you who have never heard of iStockphoto, it's a site that sells quality photos, vector illustrations, flash files, and videos for use in websites, advertising, screensavers, etc. If you're a photographer or illustrator, you can sign up and sell your own work too.
