I picked these up for either $3.50 or $4.50. I can't remember which. They work, you can see about 50 feet in COMPLETE darkness, and the only problem was that I needed to do a quick fix to the top head strap. The connection was a bit looser then I liked so I removed the mounting pin and replaced it with one of my own. Works and fits great now. Battery drain isn't that bad. 20 to 30 hours on 6 AA batteries is worth it.
