948 Crankshafts

I can attest to the difficulty of finding a good 948 crank (without going the 
$1200 billet route). My engine rebuilder rejected three cranks I brought him 
for my new 948 engine. One was from my street 948 when I converted to a 1275, 
one was a spare I had gotten long ago, and one was bought from a lister. I 
finally got one from another lister that magna-fluxed OK. I'd like to find 
another one for a back-up 948 I want to build. They are scarce.
