There are too much Sites for affialliation.
But Google is better coz , u can get Ads for your own choice, Plus different prices.
From low to hih range.....U should use google Ads ,
but still if u want to change ur taste , then try the below
www.linkscouts.com

www.worldwide-cash.net
www.matrixmails.com
www.tempscript.com
www.paidforfree.com/affiliates.htm
