Scrod,
Been on the lookout for a decent crankset used on ebay/craigslist. I see some DuraAce, Campy and Sugino 75 cranksets minus the chainring in the 100-150 range. Am I missing something or is there a reason to stay away from buying used cranks or any particular models of those makes? It seems strange to see Sram 300 for a similar price range when the Dura And Campy items are treated like unicorn horn.

Or if you have any informative links. Sanity check
