Th,is is the one I put on the tandem: http://www.acecosportgroup.com/shop/k-edge-chain-catchers.html
More expensive but more elegant too. I've used one with a hose clamp and plastic cover which was cheap enough and worked OK. I find, especially with triples, that sooner or later something comes out of alignment and the chain either falls over the outside edge or slides past the little ring. When I started riding all decent outside rings came with a post that mounted inside the crank arm to prevent this, and if the chain meant over you could usually lift it back with the derailler. I see RBW now offers big rings with this. I don't know why chain catchers aren't used more, they really do solve the inside over shift problem.
