Just a quick PSA
I had a lengthy discussion with one of the service managers in Canon Australia - And they are please to note that, although not advertised or recommended. They can perform the modification service for the replacement of their standard IR cutoff filter. It is a BYO affair - so you will need to supply them with the replacement filter. E.G Baadar ACF.
Most of the service staff do not know of this service, nor are told as this service will carry 2 conditions
1- Any warranty will be void on the camera if this service was to take place.
2- their 6 month service warranty will also not apply.
As for the price - they will do this service for AUD 314 + GST - It is more expensive than say Peter Tan. But you have that assurance that a trained canon technician is working on your camera.
I will most likely get my camera done there as, funny enough, the service manager is interested to see my results
Maybe we can somehow convince Canon to release another Da product
Cheers
