You probably don't need the scope. Most proven methods (copperhill, sensor-swaps & eclipse, etc.) clean the entire sensor, not just the obvious dust motes, which is what a scope will show you.

I paid a professional $90 to clean the sensor on my D700. If the sensor is damaged, the camera is almost worthless as a replacement is $1600.
Yeah but as I understand it you have to do something willfully bad to screw up one of these sensors. There's a fellow here that claims he cleaned his D3 with a chopstick and a napkin.
I just went to town on my D700 with a $20 visible dust kit and I can report that nothing went wrong. There's still a spot or two left but that's ok. No massive streaks, the camera didn't explode or anything.
