I think the main dial repair should not be that complicated and thus cost should be rather affordable....the shutter button is the tricky one which involves dismantling almost every part of the camera (there's a YouTube video on that).
Hi TS, what camera model do use?
Cos got experience using canon 60D, before i have tried different type of canon bodies.
But this canon 60D was different and it was my first time to used this camera.
The Main dial was not working, and cannot rotate and stuck at automatic mode. when i want to set to manual mode really cannot, then i finally found a solution the on other day.
Hehe, i found that the canon 60d got lock button for the main dial which i have nealy damage the main dial to forcely open it. my fault cos im not reading it manual.
I see, the vertical scroll right near the shutter button?
I got another fren, experience the same problem with you, when he adust the dial to the left sometimes not working but on the right direction was working.
Sometimes you need to press harder left or right this dial so you can adjust the aperture or iso.
