I have to say I favour selling a limited number of text links over using adsense at the moment. Of course this only works if your site in question has good PR. And by good pR i mean PR5 upwards. PR4 is ten a penny and too cheap, its not worth messing around with. You dont even get that much for PR5. In fact, Ive been selling pR6 links for just $10/month. But still thats $100/month on a PR6 page and its better than a pock in the eye or a slap in the face with a wet kipper.
