I recently bought one of the double-sided Kent clothes brushes from the eBay link above. It came to GBP 20.00 (14.50 + 5.50 S&H), and that was for shipping to Canada. As far as I can tell, there is absolutely nothing wrong with it, not even a dent in the handle. Seems to be a great deal if anyone is in the market for a brush.
I will point out that the package suggested that the "dark stiff bristle side" can be used for regular fabrics (e.g. wool/cotton), while the "white soft bristle" side can be used for more delicate fabrics like cashmere. Not sure if this means that having a separate cashmere brush is redundant or not.
