Cheapeast banner advertising site?

[puremage111]

previously i used freebitcoin advertising and im quite satisfy with the result and now they are closing down the advertising section.

Therefore, is there any other good sites to promote on?

$0.12 per 1000 impression might be good as freebitcoin offer that, but looking for one w/o fraud traffic, i mean it could be some fraud traffic as we can't evade it, but at least it contains more legit traffic.

Show me the list or made comparison, thanks!
