How to block ads in Opera?

As far as I know (after 1 hours of goggling:)) I've found that the solution provided by http://www.fanboy.co.nz/adblock/opera/ is the best source for blocking ads in Opera. Just download http://www.fanboy.co.nz/adblock/opera/urlfilter.ini and put it on your Opera directory (described at the begining of the file) and voi la it blocks ads.
