Mac Service center

Can anyone recommend a shop that could be trusted to install a hard drive on a powerbook 12"? I want to walk in and have it done while I wait.

The Apple Center in Hsinchu used to be ‘good enough’ but the staff I met recently seem to be a little lacking in ability.

The Apple Shop on Bade, I guess. I had a new HD installed a couple months ago. Not while I waited, but should be possible. They seem to be on the ball.
