A few days ago, i came across auction ads on shoemoney’s blog. (he co-owns it along with text-link-ads)
So i got around to registering today and was pleasantly surprised at how easy it was to setup and integrate. No waiting a few days for my site to be checked, it was automatically accepted, and i had ads up within 2 minutes 
The ads can be seen on JPEGr, basically they are live ebay auction ads for related products (photo printers, cameras, memory cards etc…). Every bid/sale/registration ebay get, i get a slice of the action. Hopefully it will earn me a few bucks on top of adsense…
