Have not heard of the term "preventative" maintenance used in this context.
Never thought of my cameras as being items which would require a "service" unless an actual fault existed be they 1, 5 or 10 years old.
As for a clean just dust of the outside regularly, internally a giotto's rocket will remove the dust from your mirror and focus screen (and I have found to work for the sensor as well).
You have not indicated that you have any bunnies on your sensor so I would suggest leave well enough alone.
Not poo pooing your thought just that money is generally hard come by and is better off in your own pocket if it does not have to go into someone else's unnecessarily.
Just my two bob's worth
I don't see the issue here or the reason for the quoted post. A car runs best where it is regularly serviced, DVD players need a regular laser lens clean, if you want your camera(s) to perform at its best why wouldn't you have it serviced from time to time. It is just being proactive. I notice that the Canon Professional Service provides for clean and check regularly (see http://www.canon.com.au/Professional/About-Canon-Professional-Services
). Whether you get it done I suppose is a matter of economics (cost/benefit really) or personal choice but that doesn't make the question (or this thread) irrational. It is just, in my books, protecting your investment, whether it be a $7.5K ID-X, a $1K 7D or a $600 600D.
