well, it might be true, might be not. at least i feel safer with VD even if it's just illusory like he says. nontheless i dont wanna spend days sneaking around to find the right brush and some awful hours testing it.
the SensorSweep seems to be a good alternative, though. but again, as i already spent a hundred bucks on the VD i dont really feel like spending some other ten bucks for yet another sensor brush. moreover, the "sensor dust" problem, i believe, will no more be an issue in the next camera generations. (Sony and Olympus already had it. there's no reason why Canon Nikon and other manuractures should stay out of it.)
for now i'll just stick with the VD & hope in a year or two i can happily trash it.
