The short answer on the Goncz light is that it would be wise to wait-and-see ... let the lights actually get into the hands of evaluators first, since we think he's taking some liberties with his specs.
The longer answer is, Goncz created quite a firestorm on candlepowerforums. Part of the problem is that Goncz is more of a tempermental genius than the kind of guy who understands how to use the internet to his advantage (contrast with Peter Gransee or Sal Glesser). Many people came down hard on him because of his abusive behavior, but I'm willing to let him slide if the products are really that good. However, when some early lights made it into the hands of some evaluators, they just plain didn't live up to specs, according to the reviews. If I remember correctly, Goncz claimed that the lamps in the early models weren't up to spec, and that the production versions would meet specs.
I remain hopeful that Goncz can pull of what he says, because the specs on his lights are dynamite. I am sceptical based on what I've seen so far, so I'd strongly recommend sticking with Surefire at this time.
