I've read that you can set the CPM basis and that you can keep using adsense and other PPC programs alongside ADSDAQ. The manually set CPM rate sounds really good, but I don't hear much about the success of this program from other members which makes me wonder if there's a catch? Have you tried ADSDAQ and did it work for you? Even if you haven't tried it, what do you think of it? Is it a good alternative to adsense with higher CPM payout?

The catch for ADSDAQ is that they only sell a portion of your ad space. I find the best success is setting the price to $2-3. It's probably the best CPM solution that I've used and their ads actually look excellent. I've actually written a detailed ADSDAQ review - you should check it out for my full opinion.
I love AdsDaQ. Great customer service and they do the job, if you get a lot of US visitors/impressions this would be a good network to try.
Is it against Google TOS to use adsdaq and adnsense together? Also, if adsaq runs out of ads to show on my site and it falls back on adsense to fill iup the space then does adsense show targeted relevant ads or are they random filler ads?
It's not against Google TOS at all - I believe that's discussed in their FAQ. As for the ads, they're pretty much the same as they would be even if ADSDAQ weren't there - targeted.
Are there any requirements your site has to meet before they accept you top ADSDAQ? Like traffic number?
