I'm going a different direction with a build and sticking with White Industries cranks. These have no miles on them. 177mm length and 48/33 rings. More info here:
I was sold these thinking that they were the Double Crankset version, but based on the 48/33 stamp on the outer ring, I believe they're actually the 9-12 speed type.
$350 plus shipping via Pirateship
For trades, I'm looking for Short Pull Post Mount Paul Klampers in black.
PM off-list
