I have a 1" Staticmaster brush I bought back in the early "80's" and when I first used it I could actually see the dust jump, ever so slightly, from the negative to the brush hairs themselves. Of course the radioactive charge has long expired and all I have now is a 1" brush. With refills costing an arm, leg and left testicle it looks like I'll always have just a 1" brush. The cost increase is far beyond the cost of inflation and I wouldn't care if I had more money than brains, I still wouldn't buy a refill knowing I'm being taken advantage of. There's a sucker born everyday, but this guy wasn't born yesterday. I'll try the Ilford cloth or just keep using my fine sable brush and blower. JW
