Vredistien have won all the autocar competitions and they are highly rated and cheap, a directional ULTRAC (18/40/225) cost me Eur160 a corner, the tyres have been designed in conjunction with Giugiaro and have a nice tread design, the closest make to them is continental (whom I think own Vredistien) which for the same size come in at 260 euros a corner. You never said what type of car your drive.
