Question about Colon Hydrotherapy...

I leave tommorrow to go to Portland, OR. I am going to look around for a good colonic Hydrotherapist. Just off hand, does anybody know of any good ones in the area?

It's the one thing I haven't tried, and I can see. One other question, can someone answer, or point me to a thread relating to colonic average prices? Maybe some additional benefits, testimonials... I feel like I need to get psyched up, heh.

Thanks, y'all!
