Edo,
Not sure what color your car is, but I definitely wouldn't have anyone use a rotary buffer on a black car.
A guy in Tigard (name and number is at work) does a pretty good job...came highly recommended, but my experiece wasn't as good as expected. He does some local NSX's, Ferrari's, and other high end cars.
A couple years ago I had a guy east of Clackamas in Boring, OR detail my black NSX...he did a great job. My only complaint, and reason for not going back since (although I will in the future) is he didn't point out a paint flaw that he definitely should have noticed due to the body shop that did the paint work recommended him. However, he did give my car a great detail.
