Another option is the Intemos cleaning system:

This is good for those stubborn blobs that won't budge with a pecpad and eclipse fluid.
I've spoken to plenty of people who wouldn't dream of cleaning their sensor themselves. When I've demonstrated what's involved on my camera screen and given them links to the copperhill and cleaningdigitalcameras sites most of them have had a go. It's not difficult and it's not dangerous as long as you make sure you're on mains power or your batteries have plenty of charge.
I've taken a relatively new camera for a "professional" sensor clean once, but that was because there was a blob that wouldn't shift however hard I tried. The repair lab ended up removing the sensor and cleaning the back of the filter to get it clean. Luckily this was done under warranty.
