I stopped by the LBS today to check out the quarq.
It's a lightly used demo without any significant wear and in perfect working condition.
Quarq Cinqo Saturn FSA SL-K Light Hollow Carbon cranks and FSA Chainrings. Like this one:

I should have asked about the warranty!! If I'm going to be covered, I'm pretty sure I'm getting it.
