Reputable Affiliate Programs

Hey folks; sorry I haven't posted here in a while.  My wife and I are considering augmenting our blog with advertising but have NO IDEA how to find reputable affiliate programs.  I have a few questions in this regard.

• Is there a (less-biased) service that compares adult-affiliate programs?
• Can anyone recommend any that has worked well for them?
  

We have modest (but respectable) traffic.  Any help would be much appreciated.
