Why are HDS Systems lights held in such high regard?

Ok, so what's the skinny on HDS lights?

They look like a nice, well-built light. I’m curious as to why the $150 price tag for an EDC has people lining up like they’re going out of style. Any current owners here? I was curious after that IS thread popped up, I had never looked into them or heard much about them, until I did a little digging. From seeing a few CPF threads they look like a better zebralight, but made in the US. Is that accurate?
