Park Tool CC-3.2 Chain Wear Indicator
I have this and it's pretty handy but somehow not all that accurate. Seems that many times I use this and the chain measures fine (<50% wear on 10+ speed chains and <75% wear on 9 speed chains), but then when I bring the bike to a shop, they measure with a more accurate device and show that the chain that I thought was ok was actually pretty well worn and needs replacement. So my recommendaiton if you want to get an accurate measurement is spend a little more money and get a better chain measurer.
