Like Mojo stated, a good headlamp would probably serve you well and falls within your $50 budget. The problem with Surefire is that the batteries must be bought in bulk. Otherwise its $8+ for a set of batteries that might last an hour or so of use. While I was stationed in Haiti, supply was clearing out their invetory and gave me a big box of those cr123 battieries. I would like to buy a Streamlight Sidewinder. Bass pro carries it for $70. This is more than your stated amount but the cost of AAs vs cr123 would save you money in the long run.
