A WebmasterWorld thread asks the question on the most important factors when pricing out a link buy.
The moderator of the forum, martinibuster, makes a clear point to say this is not about the ethics of buying links to influence your rankings but rather, if you did buy links, what factors are most important.
Martinibuster, Roger Montti, brings up traffic metrics when determining the value of a link. He said he isn't a fan of using PageRank as a metric and asks people, how valuable in terms of pricing a link is the traffic metric? I know some link builders who would prefer a high trafficked link versus a link with high PageRank, but some don't always agree.
I have a poll below, please take it and tell your friends to take it.
