First let me say that my wife Marjorie and I want to wish for every single one of you the happiest of holidays and may peace and prosperity be with you for the coming year. There seems to be a nagy little spot in my images that is caused by dust on the sensor which I just can not blow away with my Rocket blower. So I have decided to take the plunge and buy a Sensor Brush from Visible Dust in Canada, but they are very expensive so I want to buy the right one. On their site, they say that you can use either the 1.6 or the 1.3 for the D2x. There is only $10 difference in price. I believe that some of you use the Sensor Brush, so I am asking from your experience which one to get. Also is there any advantage or disadvantage of the silver over the gold finish? Another question. Since I generally do not shoot under extreme conditions usually, (not that it couldn't happen), should I pop for the full kit (about $250) or just get the brush (about $100)? The kit includes both wet and dry cleaning materials and another brush to clean the chamber housing the mirror and sensor. I have researched cleaning methods, I am aware of the less expensive options but I have definetly decided on the Sensor Brush, so I don't really need to know of other cleaning tools. But I would be interested in any feedback you might care to offer with the Sensor Brush and which conmponents you might recommend purchasing. There are some pretty good holiday package deals being offered, but I don't know if I would be spending too much to buy things that I would probably not really need or if it is inevitable that I will use it some day and should get it now and store it for that rainy day. Thanks you guys.
