Standard crank is superb, but I can see the OP's point that he cant go and buy a new one of those, so a new other make one is better than a knackered standard one.

My advice is avoid like the plague any cheap steel crank, if going aftermarket it needs to be a decent make like arrrow, not some random piece of rubbish for a grand off ebay.
If you are thinking rather than spend 500 on a mint standard crank you'll spend 1000 on a cheap aftermarket steel one, I would say thats a foolish decision to be making.

PM steveboyslim about it, he can normally get a good deal on arrow products.
