I can recommend the Kleber 'Quadraxer' tyres we had to the fronts over a year ago, done 12k and look hardly worn. They are a '4-season' tyre (as opposed to a full-on 'winter' tyre), and were better than the old ones in the snow last winter.
Can't remember cost, but I get them at 'mates rates' from ATS, where our company buy all their lorry tyres from(!)
