I have a front & rear pair in very good condition (replaced with a Russell Daylong combo when six months old) for an ST1300, located in St Helena, Melbourne. Will be away for a few weeks from Saturday afternoon, won't have time to sort anything out until Easter. If nothing else surfaces, and you can wait until then, let me know.
Price? Going rate on eBay seems to be around $350 the pair, I'd be happy with $250.
