I paid $360 for the crank itself, $55 for the Rotor BB1 bottom bracket, and just shy of $100 for both the Stronglight chainrings. It was all new. These were the best prices I could find on this stuff. The crank and BB were purchased from www.twohubs.com and the chainrings were from xxcycle.com in France.

I chose the rings because I've heard good things about them and I wanted black rings. I have Red rings on my other bike with a SRAM/Quarq power meter and I just wanted something different for this bike. I don't plan on using any SRAM components for this build.
