I agree with both Mark and Steve, i havent had much luck with brokers traffic in the past 12 months and in fact, it seems like more and more of the traffic the brokers are selling has been passed around so many times before its almost worthless to me.

PPC engines on the other hand, if you spend some time to run some tests before spending major money on a real campaign, can return some excellent results at prices less than what you would be charged by a broker for targeted traffic.
