I've been in the market for an LED headlamp that uses 123As. I was just about to order the OMS K2 here http://www.scuba.com/scuba-gear-31/026689/OMS-Ultra-Bright-K2-L.E.D.-Head-Lamp.html when I got the email from Surefire today on the Saint Minimus. Now I'm not up to date on the technology differences, but the OMS has more power and at a great price. The Minimus is a Surefire, which is a brand I have come to depend on. My use is going to be Wilderness medicine and other austere conditions. I have no problem spending the cash on a quality tool, but is the Minimus worth 3x the OMS?
