For what it's worth, I had a site making $10/day. A few months ago I moved the banner ad to the side (skyscraper) and put a full-width link unit in its place. The site is now making $20/day, of which more than half comes from the link unit. On the other hand, I've had other sites where they didn't work that well. Depends on your visitors, your topic, placement, and so on. The best thing you can do is a side-by-side test: For 50% of page views, send the layout with the link unit, and for the other 50% of views, send the one without. Let it run for a month or so, long enough to smooth out statistical noise, and then look at the channel numbers. You'll have your answer.
