Is using a face exfoliator brush any good?

Right now i am using the facial wash "clean&clear deep action cream wash" but i am thinking of buying a face exfoliator brush. People say it is gentle and good at cleaning the face and i mainly want one to make my nose free of most blackheads. Is this one good? http://cgi.ebay.co.uk/Facial-Body-Brush-… Or at least something like it? I want one but i don't want to spend lots of money on one. Thanks for the help.
