What's the difference between galvanised brake cables versus stainless steel? I'm looking at buying a set of new brake cables and I'm wondering what the difference is between the stainless steel ones and the galvanised cable?  I'm only getting relatively cheap ones but I can't find an obvious description of the benefits/disadvantages.
Galvanised ones rust eventually. Especially in the high wear areas. Stainless steel ones don't rust, but possibly don't deal quite as well with sharp curves.

Unless the extra dollar is critical, always buy the stainless steel ones. The bike shops I've been in don't even sell galvanised ones any more because the price difference is so small and the benefit so far outweighs it.
