Eastwind have entered that select group of 737 operators that have suffered an uncommanded rudder movement in flight. A more terrifying emergency for a pilot I cannot imagine, considering the sudden and usually deadly nature of this event. I read the report and after they landed the captain said he could see his knees shaking. Brave chap and obviously blessed with excellent reflexes (full opposite aileron and back pressure on the yoke within about a second). The only other incident I have heard about (other than the UA one at Colorado Springs and USAir at Philly) was a BA 737-200 on a test-flight out over Salisbury Plains (in England). Oh, and MetroJet had one during taxiing out (thank god).
Back to Eastwind, I know that the incident hurt the airline financially cos the plane was grounded for months while it was inspected and tested and they had to lease another a/c. A crash for such a small airline would probably send them into bankruptcy even if they DID make a profit on the insurance (as is usually the case in accidents, bizarrely enough).
