Might be worth looking at Flash Pro (green). They are similar quality to the Koolstops and cost about £22 (posted) for a set of 4...
Flash are very good in all conditions too. I rode a blinking hilly and very wet ride at the w/e and the brakes were fine throughout, although Koolstop Salmons may have been a better, more specific choice (specially for a heavier rider, which I am not) but I certainly can't be bothered to change brake blocks for specific rides).

Not sure how much postage will be though - probably £4!!
