Commission Junction vs Adwords and Overture

Some have compared CJ to a second rate PPC.

This is a bit off-topic but Commission Junction had been compared to a second rate PPC. I wonder if any CJ merchants can share their experience with respect to conversions from CJ vs Adwords and Overture?

The CJ terms are quite tough for merchants, besides a $2250 access fee, there is a minimum spend of US$500 per month. I calculated that we would need at least 5 conversions from CJ a day to make it worthwhile. We spend $1500-2500 per month on adwords to get around 5 conversions per day.

There are many other affiliate networks but CJ which have Top affiliates and have no set up fee or any other minimums. Top affiliate usually take part in all networks.
