I just a bought a brand new, perfect condition AGV X-Flow Replica helmet for $102 shipped. This is a $460 helmet! I've seen guys selling used knock-off brand helmets on this website for nearly twice that.

Kirk sells a lot of scratch and dents models on Ebay, and you can also get awesome deals on overstock or discontinued items (as this item was).

You may have to settle for a color/stlye you wouldn't otherwise buy, but the deals are awesome, you just have to be patient.
