I've seen varies places sell some stuff but not all of it. REI and Brightguy seems to have the biggest variety but I know there's got to be a better place for better prices. I'm looking at buying 2 headlamps for everyday tasks to hiking and mountain biking. I'm thinking about getting a PT Corona and Petzl Zippka Plus but that Petzl Myo XP and Tikka XP are looking really good, but I want to get at least one headlamp for now. I need a good close to medium range LED based lamp with lots of runtime and flood. Thanks
