Got you. I do change the chain fairly regularly for that reason. The cassette has definitely done close to 10,000km, if not more by now. On a road bike, all outside and in all weathers.
I just swap a cheapish chain early until it stops working or feels odd in the gears I use the most, although I have a dura-ace chain on now as it was silly cheap in a trade offer a couple of months back.
