I'm looking for a single cr123 titanium small pocket light. Been searching but not having much luck. Something similar to the Jetbeam TCR2 or Sunwayman V10R. Also, do they (titanium) hold up well in a pocket exposed to keys and change? I would expect some wear, but would hope they would keep their looks longer than aluminum. Also not looking to spend a small fortune, preferably in the $100-$150 range, or less would be good! Any ideas?
