Agree totally.
I have interacted with the service people twice in about 7 years. And with equally positive experiences.
First time, there was a free upgrade on my SD722 to version 2.0, allowing it to record to external firewire devices. My 1.0 version did not support this. No cost except for local shipping here in Sweden. Great experience.
Second time, changing the hard drive myself, managed to strip one o the long screws holding the box together. Mailed SD and a few days later, free of charge, came a set of extra screws.
This is professional level quality!
