I use adsense on a couple of prime spots and some defaults but recieve better rates from Burstmedia, Valueclick and Tribal Fusion by using their defaults and capping with the software I use (open x). My overall net is about $0.75 cpm.
Adsense makes it difficult to compare their rates because they count individual ads (sometimes 4 in a 160x600 creative). I count the whole box so I can compare them to the others and find they average about $0.32 cpm. I also use a Canadian company called Casalemedia (which pays similarly) at the end of a chain.
Fortunately I signed up with these companies years ago by starting my own ad network of similar sites. I later dropped the other sites as my own traffic grew. Except for Valueclick they are all considerably more difficult to sign up for these days.
