For finding new (super) affiliates check out the "
Affiliate Recruiter" by
Syntryx. It's not cheap, but worth it, if you are serious about your affiliate program. The service is actually more than just a locator tools affiliate partner, but it has several special features that were created just for this purpose.
It's a full blown
competitive intelligence tool to sneak up your competitors and see what they are doing.

a good post at ReveNews.com about her review of the service in May 2007.
Also worthwhile reading IMHO is my post about "
What (Super) Affiliates Want" at ReveNews.com from July this year.
Cheers!
