Adbrite v. YPN v. Other

I currently am signed up to both Yahoo Publisher and Adbrite. However, I am getting almost NO clicks at all in YPN, although I used to get quite a bit from them. Adbrite is consistently about 4 cents a click. I’m wondering what you guys think about joining another program like Bidvertiser.
Any1 want to shed some light on what route I should take with my advertising program?
