Looking for adsense compatible CPM sites

Hello all,
I have a free advertising classified site , where I have 5 ad slots, I am using the top 3 for adsense, I still have 2 slots pending . I am planning to monetise them with a good CPM site, since they would be placed below, I don't expect a high CTR rate . Please share a good ,reliable and adsense compatible CPM site.
