Affiliate income is good source of income with your website. But one thing I must say that build a website related you your interest and after that try to monetize your website. It will be more beneficial in ling term.
PPC is biggest source of income for me.
In PPC, Adsense is biggest contributor and am getting some additional contribution from Adbrite and Guruji ads....
Affiliate programs may replace PPC in future. (They seem to have a better ROI, but I haven't worked much with affiliate programs).
note: when you replace this, dont use masked URL. thanks ~ admin
