If the link is in a prominent position, and you offer a product that is highly targeted to the site's content, you can do extremely well. Not to mention you could get a great PR boost - up to PR 7 likely.
However, I get the feeling that the abovementioned situation is much closer to the one you are in.
It's unlikely you'll find much frank and open discussion about how much a link from a PR8 page is worth. Consider the link in terms of typical advertising costs and the ROI you can expect from it.
