I have hunted with Burbank, Mardon Duck Taxi, Pacific Wings and had fantastic hunts with each and not so fantastic hunts with each. If the conditions are sub par no one can make birds happen. I evaluate them on service and effort and honesty.
I can't remember if the OP asked about seaducks but someone responded with a few seaduck guide references. All I can say about that is ask to see their US Coast Guard license and TWIC card before getting in the boat. It is required for any passenger for hire vessel on Puget Sound and Columbia River.
