Anyone know of some 'decent' ones. The Sigma supplied ones won't
attract a whore in a crack house. The Bosch type ones always seem to
corrode and fall off, and on top of that are easy to X-Thread. The
Cat-Eye ones don't seem to stay put[1]. The Echowell/Yamaha ones seem
pretty decent but are like rocking horse **** this side of the pond.
Any other ideas?
