For Sale: Stages SRAM X9 BB30 MTB Crank

I am changing bikes which will require a different crank.  I had the power meter mounted to a 2011 Specialized Epic Expert for less than a year.  It worked great and I did not use the drive side, therefore the chainrings are still new.  I'm asking $500, it is $899 MSRP.  Email me if you want to see pictures.  

Here is the info from the Stages Cycling Website.  
 
For SRAM mountain riders we offer a Stages Power meter available as a Power meter only non-drive crank arm for existing SRAM GXP and BB30 model cranks. Riders looking to add power to their existing crank will need to select length, and bottom bracket spindle type to retrofit a Stages Power meter to their X9 system. For those riders looking to purchase an entire crankset with a SRAM X9 model, we offer the same Stages Power meter options mated with either a X9 GXP or BB30 drive-side crank with 39/26t chainrings.
 
(Note: X9 GXP is compatible with X7, X9, X0, XX [166 Q model], and many Truvativ GXP models)
