Newegg has it in stock, right now.
I wonder how it compares to Scythe's Big Shuriken 2 Rev. B. I was just about to use one of those in a mini-ITX build. It has 5 heatpipes that are looped around to touch the fins on both ends (does that count as 10 heatpipes?). It's basically the Kozuti with 2 more heatpipes and a bigger fan on top, instead of the small one underneath the fins. I'm currently running one (lapped) in a 3.6 GHz quad-core Sandbridge-E (130 W TDP) system with a Noctua 140 mm round fan. It stays below 70 C, under full load. So, I think it's pretty good.
My beef with both of these coolers is that neither is direct touch. But I guess Xigmatek or somebody probably has a patent on that. I wish I had the tools to grind down the block and convert it to direct touch, myself.
