These are some other ppc search engines:
Findwhat.com
Goclick.com
Enhance Interactive (ah-ha.com)
Kanoodle.com
Epilot.com
Search123.com
SearchFeed.com
Espotting.com
Xuppa.com
They are not all recommended, and I suggest you do a search on them on this board before deciding anything.
There is quite a bit of info on many of them.
I am hoping that some of the ones with the really bad affiliate fraud will clean up their act in an attempt to garner a good share of this new market.
If I was them I would make sure each and every click was perfect.
Doubtlessly some of the scumballs will remain scumballs though.
