Suggest Ad Platforms that are low cost or free

[blogginginc]

I basically need to server ads to my own network. We are talking about thousands of impressions, but not millions daily.

What are the best (if any) ad platforms out there where I can run and serve my own ads at a low cost (or maybe free).

Thanks.

Direct CPV, 7Search are very low cost and can cost pennies per view. However you do need to make a deposit with Direct CPV

Check out OpenX (Open source ad serving platform for publishers | OpenX | OpenX)
Its free, open source and easy to use. I also found this (OASIS) but I've never used it.

I'd 2nd the suggestion for OpenX if you're looking for free.

On the paid side, you could check out AdShuffle. Pricing decreases with volume.
