I've broken at least 10 cranks - mostly cheapo sucky Galli cranks because I couldnt afford top gear when I was a kid, but a few other different brands as well. Sugino, Sun Tour Supurbe Pro, Shimano, Galli branded Stronglight. Must be something about the letter S.
Most of them broke or cracked at the pedal, but I've broken them half way up the crank arm a few times. Right side, left side, doesn't matter.
My father has broken at least 5 cranks over the years, and I know a guy who has broken more than both of us put together - including numerous Campagnolo cranks.
With enough use anything will break eventually.
