Guided tours around Taiwan

My parents are coming from the United States to visit me in Taipei during Chinese New Year, but they want to tour the country beforehand. I would not want to leave them up to their own devices (they’ve traveled before, but always on tours), so I’m looking for a decent English-speaking tour group they could go with. It doesn’t really matter how long the tour is, just as long as they get to have a good experience and it gets them to Taipei by the start of the holiday. Price is not an issue.

Any suggestions?

Eddie of Green Island Adventures is taking tourists on trips around Taiwan. I know he just bought a VIP bus. This bus will also run every Saturday to Sun Moon Lake and Puli. He just took Australian engineers and their parents on a trip and they were very satisfied with his professional service and knowledge Taiwan.
