If it's a cheap tyre your after, look no further than the Uniroyal RainSport 2, you won't find a better tyre for the money. Camskill have them in stock @ £37.40 each including VAT, a pair would be about £80 delivered.
Just to give this a bit more info
Got my uniroyal rainsports on yesterday, and I find them much better than the toyo proxes I had, seem a little stiffer but the grip is amazing for the price, and you actually feel like your on the ground where as the toyo's felt a bit light.
