As you know there are few cleaning systems around at the moment.
My personal choice is the visibledust system, using sensor brush and spinning device.
plus using the sensor swabs with the visibledust cleaning fluid.
The system is very expensive at £199 for the whole kit.

I photograph a lot of motor sports and extreme sports so the enviroment can by very dusty and with lense changes you cannot help but attract dust to to the sensor.

I found that just using the sensor swab and eclipse cleaning fluid just moved the dust to the edge of the sensor when you swipe it across.

But as i said my sensor needs cleaning often , and not everyone is in the enviroment that i work in. so for general use i would go for the sensor swab and eclipse cleaning fluid.

And as BETH pointed out you can always use fixation, they repaired a canon 1d for me a few months ago cant fault them there service is first class.
