tweezerman.com makes a real badger hair shaving brushes that retails for $10.00 with a lifetime warranty. I know they don't compare with the expensive silver tips but they work just fine and don't cost much more than a boar bristle brush. If you go to tweezerman.com they have a search engine so you can check local availability. I haven't tried the internet site below but they ship free so if they are not available locally you might want to try ordering from these folks.
