Also you should look into the radioactive static master brushes, which is also a great brush for dust but pricey. I have one I got in a kit of stuff awhile ago, but I think now it needs a new cartridge. But still performs nicely as a regular brush lol.
I ordered one direct from Kinetronics in Florida. I can't recall how much the shipping was but I don't think it was that expensive. A very pleasant company to deal with.
sharperstill,
My memory is a bit hazy. I think I emailed first, then they told me to put it through the online system and put the state and country in the "comments" field. I would email first.
