I've had the cheapo beaters on mine for about 3 months now, no problems as yet but they do seem a bit flimsy. Wish i'd gone for the stainless versions. MTB forums also seem to agree that the cheap ones are prone to snapping. I also worry that they're allen-key only (can't use pedal spanner to remove) so if you round the allen hole, you're stuffed. That said, they do look ace and they're piss easy to clip in/out.
