+1 for the Corsair HX series. I build pc's for friends, neighbors, and girlfriends. I use Corsair exclusively. They psu's are high quality and very stable.
From time to time online vendors will have a special sale, mail-in rebate, and free shipping simultaneously. Right now buy.com has the Corsair 750TX for a final price of $80.99. Unfortunately as others have pointed out it is not a modular psu. Don't know what prices are like in your country.
