If I were you, I would wet clean it myself.
My local Nikon dealer offers free sensor cleanings for life if you buy your camera from them. I do not know what they charge otherwise. However, due to their poor return policy (no refunds and 10 day exchange), I seldom purchase from them anymore. Even if somebody does it for you at no charge, it takes a lot less time to just do it yourself, and I am fairly certain I can clean it as good as they can.
Oops, I just noticed I replied to the very old OP. Regarding the automatic sensor cleaning feature, I use it but have never really noticed that it helps. When I see dust, I like to go ahead and take care of it rather than waiting while it sits there and possibly becomes more difficult to remove.
