He is a big list of PPC sites http://www.ppcadcenter.com I used to use a bunch of them but now I only use adwords. Who are you currently using?
I only use adsense, but it takes a long time to convert its check to cash why don`t you use any other service?
Can you know any other way to get my money from adsense except their check? that check made me mad, it takes long time to be delivered
