Sorry, but I use the 724, not what you wanted to hear.
I know you are on a budget but a word of caution. There is dust, there is sticky dust, and there is oil/gunk. If you don't know what its likely to be (perhaps the camera has never previously had oil cleaned off the sensor) a wet clean is the best thing to give you a datum point for your camera. If you use an Arctic Butterfly on oily gunk it contaminates the brush and it will need cleaning, and it won't remove the oily gunk anyway. So I recommend a wet clean to be sure you have sticky dust and oil removed, then the Arctic Butterfly will be great for intermediate cleaning. Oily gunk does become a rarer problem the more the camera is used.
However if you bought it from a dealer maybe they could confirm if the sensor had a wet clean before you got it? Its still best to know for sure though by doing it yourself.
