Been commuting using a Vega for 2 years - I like it because it is self-contained, has a blink mode for urban/suburban lighted streets and puts out what I consider the minimum acceptable amount of light for dark streets and paths. That said, I'll probably replace it this winter since there are newer lights out there that provide better light and run time for a similar price.

If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
