Best Affiliates

Dear People,

We are thinking to sign up to a decent affiliate program,any genuine recommendations without having a financial biased? I guess we should be looking for Bookmakers with a decent bonus that are relatively new to the market or less exposed?, i can´t see the point in being affiliate number 2500 for William Hill (example),so without trying to sell us on something,any suggestions?

Thanks

BGO seem pretty good, and they have a great looking website.
Edit: Not bookmakers though, but a good program nonetheless.

Betting Partners is excellent
