best affiliate programs

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I've tried a number of affiliate programs and most of the are not
worth my time.  But I've made money off a few of them (ancestry,
globat, and adwords).  I realize that success is dependant on traffic
and having ads that are relevant to your page.  I was wondering what
affiliate programs anyone has had success with.

I'm sceptical of sites selling products which will help boost your
site's rank, but has anyone ever checked out ?
It has a PR6, but I know that may not mean anything when all is said
and done.

Thanks in advance,
