I don't live in WA, but I thought I'd throw this suggestion out there while we wait for WA residents to find this post and reply!
Obviously as a non-resident I dont have much info, but
you may want to look into Northwest Weight Loss Surgery in Kirkland WA. Their website is at
http://www.nwwls.com/
The reason I know of them is that one of the people who works there (Jessie Ahroni) spends A LOT of time answering questions on the SmartBandsters mailing list over at yahoo, and she seems to be great at dealing with band issues.
Good luck finding a doc that you're comfortable with.
