I am looking for some alternatives to the main PPC providers.

So far I found:

7Search that seems to have decent reviews,
OpenX but they have an minimum payment requirement of usd1000,
AdBrite but they seem to focus on big spender,
Chitika who is doing a lot of advertisement for their own product but I could find only reviews for their adsense type of product,
Clicksor, for which I found some complain from publisher but not nothing from advertiser,
Miva and ABCSearch but I found mainly bad reviews,
…

I wouldn't mind to use several small providers but I don't want to throw money out of the window!

Unfortunately most articles which compare different providers are either 2-3 years old or not dated.

Did you test any of them?

What are your comments?

What else would you suggest?
