How to find a reliable domain broker for domain names?

Which is the best way to find a reliable and honest domain broker for domain names? Have you used the services of any domain broker?

I usually do domain flipping all by myself as I have some good experience at it. But if you need domain brokerage, you can check Sedo as they have domain brokerage service you are talking about.

Sedo fees for domain brokerage are very high. Do you know of a smaller broker who will take a percentage of the domain price.
