Hi Aaron Im in the Seattle area too and the closest you'll find training is with Brock Steiner from Vancouver WA ( username brs on this forum ) who fly's with Sport Copter but thed last time I talked with him he didn't mention that you had to purchase one of their machines but I know that has been the rule in the past with SC.
I plan to continue my training down in Utah at Airgyro with Micheal Burton, that is the next closest training I could find around here. They are a really good outfit and you can find some of their training video's on You Tube.
You can check out the PRA website for a list of instructors also.
Do you currently have a machine ? Any gyro hours ?
