php affiliate? or other affiliate programs on php languge?

hi, i am looking for an affiliate program (good freeware or good cheap commercail software). i went to http://www.hotscripts.com to look in its php scripts - affiliate category. not too many to select from. anyone has experience in any of them or other php based affiliate program? please share your experience with me? any information you think that will help. how about the "php affiliate"? it seems that it was an old one. but the "php affiliate" only has a new forum with only 30 posts and i think "php affiliate" team is busy in making the new commercial version. i cannot find good help in the php affilate free version. any help? better if I can find a good affiliate program supporting 4 languages English, French, German, and Dutch, that will be great. Thanks!
