Sorry for being so late to the party...

Even if you can find a used German crankshaft, you really can't tell how much it has been stressed even if its not showing stress cracks. There are aftermarket options that are available: both Scat and AA sell chrome-moly lightweight cranks for $2250 and $1200, respectively. AA also offers a billet crank at around $1800.

I have had a broken crank happen in my 912 and even with a replacement German crank and ~40,00 miles, I opted for a new crank. Be aware that these cranks are being forged in China with finish machining being done stateside. I understand that AA quality is very good at this point. It may sound like a lot of money to spend, but it buys peace of mind...
