Need A Good CPM Network… Any Suggestions?

My website is currently averaging right at 20,000 unique a day and increasing steadily. My current CPM network rates just dropped down to .12 CPM from .60's after the holidays. Have to find something better… Just applied to Tribal Fusion, but still have a feeling they're going to find a reason to decline me.
Any good suggestions with at least .50 CPM rates?
