Richeson "Magic" Brush

I have often seen mention on the list of the wonders of the Richeson 9010 brush.  I'm looking for a better brush to get smoother coatings of liquid emulsion on various papers.  When I checked out what I think is the so called "magic" brush, it appears to have a metal ferrule.  Isn't that to be avoided?
Advice on the Richeson, or other wonderful brushes, welcomed.
