I used Michael Herlihy (contact info below) when I bought my boat about 15 months ago and was quite pleased. I believe I got his name from this Ericson site. Kells Christian, of the same office, is also highly regarded.

I used a surveyor based close but outside San Diego County for my San Diego boat, thinking I might escape any "old boys' club" entanglements. Would not recommend the surveyor I used, and can give further details by private e-mail to bona fide potential Ericson purchasers only.
